Avast Pro Antivirus 18.4.3 + license key Latest Version November 9, 2018 Anti-Virus, Full pc software, free download, Windows 0 77 avast pro antivirus license key is a very powerfull software for windows operating systems likes Android, Windows, Linux, and Mac OS X. Sep 18, 2017 Avast Free Mac Security provides very good antivirus protection for free, and it throws in email scanning on top. Unfortunately, this software doesn't offer any other perks that you can't find.
A good antivirus program is essential to a secure system, and you most definitely do not have to pay for one to get great protection. Below is our hand-picked list of the 11 best free antivirus programs that you can download for Windows today.
All of these programs perform definition updates automatically, are always running to make sure your files are protected from malware and your personal information remains private, and can start scans on-demand whenever you like.
- Sep 27, 2016 Pros / Avast detected every Mac malware threat we used during testing. Cons / This program doesn’t automatically scan USB files when you plug drives in. Verdict / Avast Security for Mac is good software for detecting both Mac and Windows malware plus offers extra protection with its password manager and VPN.
- Best Mac Antivirus Software. You need an antivirus program on your Mac. That statement may cause some Apple users to argue or walk away, but 2017 has so far seen more Mac malware and adware than.
However, each of them do have a few prominent differences that make them stand out, so pay attention to those as you decide which one to use.
If you're looking for protection on your other devices, check out our list of free antivirus apps for Android and best Mac antivirus articles, too.
If you just need a spyware cleaner, and need it right now without waiting for one of these full AV programs to install, use one of the (preferably portable) applications from our Best Free Spyware Removal Tools list. There are also free on-demand virus scanners you can install. Also consider installing a Windows Firewall alternative from this list of Free Firewall Programs.
If you can't even log in to Windows to install an antivirus tool, access a computer that does work and then use it to make a free bootable antivirus tool that you can then run on the infected computer.

Avira Free Security Suite
What We Like
- Password manager included.
- Optional additional downloadable protection layers.
- In-the-cloud antivirus process.
What We Don't Like
- Additional features can be annoying.
- Only protects Chrome and Firefox browsers.
- Add-on components often require fee to be fully functional. Download icon pack mac os.
The main component in Avira's free software suite that makes it stand out is the optional 'in-the-cloud detection' feature called Protection Cloud. This scanning method lets Avira's antivirus tool identify and stop threats before they get out of hand.
This is how it works: When a suspicious file is detected on any computer running Avira, a fingerprint of that specific file is generated and uploaded anonymously to Avira so that they can scan it and report its status (whether it's safe or dangerous) back to every Avira user so that the program can take appropriate action.
Avira can scan and remove existing threats as well as automatically detect and stop new ones. It protects you against ransomware, Trojans, spyware, and other kinds of malware. You can even choose which ones to actively watch out for, and disable others (though it's not recommended) like dialers, jokes, adware, etc.
- Scan on a schedule
- Check files with any file extension or just the ones you manually choose from
- Disable the ability to stop active scans (so that viruses can not stop the program from finding them)
- Adjust the scanner's priority level
- Scan master boot sectors
- Follow symbolic links to scan the actual files
- Search for rootkits before starting a scan
- Scan the Windows Registry
- Ignore files on network drives
- Automatically repair, rename, quarantine, delete, or ignore threats when they're found
- Use heuristic scanning
- Add files, folders, and processes to the ignore list
- Manage Windows Firewall settings
- Password protect the program's settings
- Block autorun on removable devices
- Make the hosts file read-only
The Avira suite offers more than just a very extensive antivirus application. It includes several other 'layers' of security that will install automatically, and they might take a while to download since there are several. However, you don't have to use them and they won't bother you unless you open them.
These separate modules include a VPN that encrypts all your traffic (up through the first 500 MB each month); password manager to securely store complex passwords; and software updater that identifies outdated programs and gives you the download links to update them.
In addition to those, Avira can speed up your computer and reduce boot up time with its tune-up tool, help you find the best deals as you shop online, and warn you of malicious websites or software bundles before you download them (with its SafeSearch add-on).
These extra features can be annoying if you're strictly after an antivirus solution, but again, you don't have to use them; just keep them tucked away where they are and you won't have to worry about them.
Avira Free Security Suite is intended to run on computers with Windows 7 SP1 and newer, including Windows 10 and Windows 8.
There's also Avira for macOS that's similar, but not exactly the same, as Avira for Windows. Namely, the Mac edition is only on-demand, meaning that it doesn't check for viruses automatically like the Windows version.

Bitdefender Antivirus Free Edition
What We Like
- Drag-and-drop file and folder scan.
- Minimal, uncluttered design.
- Simple to set up and run.
What We Don't Like
- Limited customization if you're looking for that.
- Large initial program download.
If you want an antivirus program that's not only free but super easy to use and not cluttered with lots of buttons and menus, you should definitely try the free version of Bitdefender Antivirus.
You not only get instant protection against viruses, worms, rootkits, spyware, and other threats, but also anti-phishing and anti-fraud protection to carry security with you when you're browsing the internet and entering passwords.
It's actually remarkable how well Bitdefender runs despite its minimal design. You can drag and drop folders and files directly into the program to instantly run a scan against them, as well as immediately start a full system scan or scan select objects from the right-click context menu—all of which can run at the same time.
Regardless of how they're started or how many scans are running simultaneously, a history of those scans are recorded for you on the primary window of the program as well as within the Events area of the settings.
The obvious downside to a program that lacks many customization options is that there isn't much you can change about it. That might be something you want but it might not be available; so be aware that basically all you can do with this edition of Bitdefender is start and stop scans.
Another downside to this software is how long it takes to become ready for you to use. The initial installer for Bitdefender is quite small but that's just what's used to then download the full program, which is hundreds of megabytes and could take a while if you have a slow internet connection.
It's also unfortunate that you can't pause scans (it just lets you stop them) or set up file and folder exclusions before starting scans like some AV programs allow. With Bitdefender, you can only mark files or websites as safe after they've been identified as malicious.
Ads asking you to purchase Bitdefender's professional programs and scheduled scans not being supported (but they're not necessarily needed since Bitdefender is always checking for new threats) are a few other not-so-greats.
Bitdefender Antivirus Free Edition runs on Windows 10, Windows 8, and Windows 7. You can also get this free antivirus software on your Android or Mac.

Adaware Antivirus Free
What We Like
- Lightweight antivirus program.
- Can run as a supplement to other antivirus programs.
- Silent mode mutes notifications and limits resource use.
What We Don't Like
- Some useful features are only usable with paid version.
- Limited configurability.
- Email scanning not included.
Adaware Antivirus installs in minutes, is light on system resources, and can be used in one of two ways. The first is in regular mode where it checks for threats as they happen, but the other lets you use it in addition to your 'main' antivirus program (i.e., along with Bitdefender or Avira).
What this so-called 'second line of defense' does is disables real-time protection but still lets you use Adaware Antivirus to manually scan for existing threats. This is helpful if your primary AV software doesn't seem to find malware that you know is infecting your computer.
Whichever way you use it, Adaware Antivirus provides a defense against ransomware, spyware, viruses, and other forms of malicious software. You can find those threats through a quick, full, or custom scan.
Daily, weekly, and monthly scheduled scans are supported, and you can even run a scan to just check certain things, like only rootkits or just tracking cookies and boot sector viruses, for example.
Adaware Antivirus also lets you choose a custom performance setting to use more system resources to run the scan (to make it faster), exclude files/folders/file extensions from scans, and decide how often to check for new definition updates (every 1/3/6/12/24 hours).
When it comes to real-time protection, you can toggle on or off the following options:
- Scan archive files
- Scan email databases
- Deep scan that checks CHM files and executable files
- Smart scan that skips previously checked files
- Scan boot sectors
- Scan files as they move throughout the network
- Skip scanning files that exceed a custom file size (e.g., 10 MB to skip video files)
You can also protect the program's settings with a PIN as well as enable gaming/silent mode to suppress notifications.
Adware Antivirus definitely has its advantages but because there's also a non-free version you can upgrade to, many additional options are not supported.
For example, parental controls and advanced network, web, and email protection are only available in Adaware Antivirus Pro. These options are visible within the free edition but they're not actually clickable/usable until you enter an Adaware Antivirus Pro license key.
Adaware Antivirus Free works with all versions of Windows.

Avast Free Antivirus
What We Like
- Add-ons allow you to increase protection.
- Great customizability.
What We Don't Like
- Password manager and some other tools included are trial only.
- Additional features require purchase.
Avast is used by hundreds of millions of people and ranks high in nearly every 'best list' of antivirus programs, and for good reason. If you want a solid program that is sure to block new threats but is still easy enough to customize, you should consider using it.
Avast Free Antivirus is similar to Avira which we mention above; there are numerous components that you can install along with the virus shield that provide additional services related to security and privacy (more on those below).
The antivirus portion has lots of options you can change but it's still easy enough for anyone to use since there are information blurbs next to most items so you're not left wondering what will happen if you enable them.
Plus, both definition and program updates are performed automatically (a manual option is available, too), meaning you can install Avast and let it do its thing without worrying whether you're running the latest and greatest version.
Avast is highly customizable and lets you make changes to everything from whether to make a sound when threats are detected and how long notifications should remain on the screen, to the kinds of file extensions that should be scanned.
Here are some more features supported in Avast Free Antivirus:
- Scheduled scans
- Custom scans that can check only the memory, rootkits, auto-start programs, etc.
- Checking all files or just certain file extensions
- Identifying files by their content instead of their suffix
- Fine-tuned heuristics sensitivity
- Scanning for potentially unwanted programs
- Follows shortcuts to scan the real file
- Can scan within lots of archive file formats like self-extracting DOS and Win32 executables, CHM, ACE, 7Z, RAR, TNEF streams, Mac archives, ISO, and more
- Windows Explorer context menu integration
- Folders, HDDs, and URLs (but not specific files) can be pe-excluded from scans
- Custom scans are easy to save for use in the future
- A Rescue Disk can be created that lets you use the Avast scanner even if you can't start your computer
- Particular areas of the program can be protected with a password
- Lets you enable Do Not Disturb Mode to deny notifications from other apps while you're using one in full screen mode
https://costnew944.weebly.com/avast-security-pro-for-mac-deals.html. Before Avast is installed, you have the option to include over a dozen different tools: file, behavior, web, and mail shields; software updater, browser cleaner, rescue disk, Wi-Fi inspector, security and SafePrice browser extensions; password manager; junk file cleaner; and Game Mode.
Technically, if you only want the antimalware protection, you can install just the shields from the start of that list; the others are add-ons that aren't necessary but could be helpful at some point.
For example, the software updater is a nice tool that will not only check for and report outdated software but also install the newer versions for you (even in bulk). This is a great way to make sure your programs are up-to-date with their latest security patches and features.
Wi-Fi Inspector scans the network for devices that could be vulnerable to attacks. For instance, it might identify that a computer is running a file sharing service that has been known to facilitate the spread of a certain kind of worm.
You can install these tools (it takes less than five minutes) and then disable or completely remove them later. Or, you can ignore them during setup and just install them later, or not at all.
However, please know that the password manager and Cleanup tools are only trial versions that will expire after so-many days. There's also a firewall, file shredder, and sandbox feature that's unusable in this free version.
Avast Free Antivirus is compatible with Windows 10, 8, 7, Vista, and XP.

Panda Dome
What We Like
- Light impact on system resources.
- Substitute for milk in mac and cheese kraft. Minimal, uncomplicated design.
- Security news about the latest reports of breaches and threats.
What We Don't Like
- Resets browser home page and default search engine unless specifically deselected during installation.
- Contains advertisements.
Panda Security's free antivirus program, Panda Dome (previously called Panda Free Antivirus), installs in minutes and has a minimal design like Bitdefender, mentioned above. However, even though it's not a CPU or memory hog, and doesn't appear to be customizable, all of its many options are tucked away in the settings.
From there, you can do things like set up both on-demand and automatic scans to check compressed files and scan for potentially unwanted programs.
The automatic, permanent scanner includes some additional options, too, like behavioral and analysis scanning options, the ability to ask you before neutralizing a virus, and blocking files from running for so-many seconds until results on whether it's safe or harmful are obtained from the cloud.
Something entirely unique to Panda Dome is its security news and alerts sections that can show you critical, warning, and informational messages like when a popular vendor experiences a data breach that could affect your personal information. You can, however, turn those off if you want to. Image workflow software for mac.
You can complete a scan in just a few minutes if you only want to check for actively running threats, like browser cookies, processes, and things currently loaded in memory. However, there's also, of course, an option for a full system scan or a custom scan.
Here are some other things you can do with Panda Dome:
- Password protect the entire application
- Have the quarantine emptied every three days, every week, every month, or never
- A gaming/multimedia option will disable all notifications if you're using a full screen application
- Exclude particular files or folders from scans, as well as specific file extensions of your choosing
- USB protection can be enabled to always scan removable devices as they're attached, to make sure that they don't spread anything to the computer
- Monitor running processes as well as any URLs accessed by them, and have them terminated if Panda Dome deems them a threat
- Record everything in event reports that you can browse through and even print or export to a TXT or CSV file
- Can optionally install Panda Safe Web during setup to protect you against malicious websites
The Panda Dome antivirus software does a really good job at keeping the important buttons up front and hiding the additional options within menus so that you're not constantly bombarded with options or alerts.
However, the program will change your home page and the search provider in your web browser, unless you uncheck those options during the initial setup.
Panda Dome works in all versions of Windows from Windows 10 back through Windows XP.

AVG AntiVirus Free
What We Like
- Installs in a few minutes.
- Choose what to enable during setup.
- Updates automatically (definitions and the program).
- You have full control over how things work.
What We Don't Like
- Shows features you can't enable in the free version.
- Always advertises AVG Internet Security.
- Doesn't officially support Windows Vista or XP.
AVG's free antivirus program is easy on the eyes and even easier to use. The scan button is right in the middle of the screen, turning features off is dead-simple, and all the advanced options are tucked away from view in the settings.
Like most antivirus tools, this one lets you schedule scans, check for threats in archives, remove viruses right when they're found, scan USB drives, exclude files/folders/websites from scans, and run boot-time scans.
It's worth noting that AVG AntiVirus Free is highly customizable. You can either install it and leave the settings alone to have regular protection, or you can go into the settings and make adjustments to nearly anything.
For example, you can have viruses and PuPs fixed automatically or be prompted to take action, enable/disable scanning of downloaded files and scripts, scan inbound and/or outbound mail, check/skip the scanning of MS Outlook attachments, check or don't check for threats on inserted discs, and scan all archive types or just the most commonly used ones.
Another important feature in AVG's antivirus software is the option to choose how to scan files. You can have the program scan only the files that contain content that might include malware (like executable data), only files that are using a file extension considered potentially dangerous (like EXE), or all files regardless of content type or file extension. https://renewcases.weebly.com/blog/master-writer-free-download-mac.
You can also enable rootkit detection, hardcore mode (recommended for inexperienced users), and CyberCapture technology, which helps detect threats in unrecognized files.
During setup, you have full control over which components should be enabled or disabled once AVG is installed. Options include File Shield, Behavior Shield, Web Shield, Email Shield, SafePrice browser extension, File Shredder, Cleanup, and Do Not Disturb Mode.
AVG AntiVirus Free includes a file shredder tool as well, which you can use from the right-click context menu to overwrite files using the Random Data, Gutmann, or DoD 5220.22-M data destruction method.
Windows 10, 8, and 7 are supported. It also runs on Mac (10.10 Yosemite or above) and Android (5.0 or above).
You're asked during setup to also install AVG's web browser, AVG Secure Browser, but you can uncheck that option if you want.

COMODO Antivirus
What We Like
- https://costnew944.weebly.com/blog/avast-for-mac-installation. User interface can conform to your comfort level.
- Lots of settings can be customized.
- Run programs virtually.
- Automatic updates for the program and virus definitions.
What We Don't Like
- Settings sometimes don’t save after editing them.
- Includes other programs and tools you might not want.
COMODO Antivirus excels in a few ways: it can be as simple or as complex as you want it to be depending on your experience level with antivirus tools, it supports cloud-based scans to detect new threats, and the built-in sandbox technology can isolate programs so that they can’t affect your files even if it they do turn out to be malicious.
Right after installing this free antivirus program from COMODO, a scan is started immediately to make sure your computer is safe as soon as possible. You can also run scans at any time, either quick scans, full scans, scans of commonly infected areas, and custom scans.
A custom scan in COMODO Antivirus lets you choose which files or folders to scan and enables a host of other customizations like whether to decompress and scan archives, use cloud scanning, automatically delete threats, enable heuristics scanning, check for threats running in memory, skip files over a maximum size, run the scan with full system resources, delete PuPs, and more.
Provided in this program are two ways to view the settings and features: basic and advanced. The basic view lets you run scans, unblock applications, update the program, and run software in a virtual mode, while the advanced view includes more details about those areas of the program and lets you view logs as well as toggle various things on or off, like HIPS and VirusScope.
It’s important to not overlook the virtualization feature in COMODO Antivirus. You can run any program you want in a virtual space completely separate from the rest of your files. It’s an opportunity to test out an application to ensure that it’s real and not just a trick to get you to install a virus.
However, even if it does contain something malicious, your real data (photos, videos, documents) are unaffected. You can launch programs in this protected container from inside the COMODO program or by right-clicking an executable file and choosing the option in the menu.
- Password protect the program
- Utilize a floating desktop widget
- Hide the “Upgrade” advertisement
- Choose which archive file types to unpack and scan
- Enable real time scanning of files on the network
- Define heuristics scanning level (low, medium, high)
- Schedule scans as frequently as every hour to as infrequently as once a month
- Customize the HIPS rules
- Turn on Silent Mode in seconds
- Force the auto-containment of suspicious or malicious files
- Use a unique password for the Virtual Desktop feature
During setup, you can also install Internet Security Essentials to protect against main-in-the-middle attacks.
COMODO Antivirus officially supports Windows 10, Windows 8, and Windows 7. It's also available for macOS.
The COMODO Dragon Web Browser automatically installs during setup unless you tell it not to. After installation, pay close attention to the options you’re given — you can change your DNS servers to be the COMODO Secure DNS servers (which presumably improve security and speed up browsing), enable Cloud Based Behavior Analysis, send anonymous program usage to COMODO, and change the home page and default search engine to Yahoo.

FortiClient
What We Like
- Automatically downloads and installs updates.
- Lots of control over the settings.
- Simple user interface.
- Comes with an application firewall.
What We Don't Like
- Requires the internet during setup (it’s not an offline installer).
- Slow to download and install all the components.
- Unable to pause scans (only stop).
- Lacks helpful documentation.
The FortiClient free antivirus program is unique for several reasons. Unlike many of the other AV programs on this page, this one includes parental control features, can manually check your programs for vulnerabilities, functions as a VPN client, and includes a firewall.
Installing this program lets you block websites by URL and/or site category, such as bandwidth-consuming sites, illegal sites, and ones flagged as including content relating to hacking, discrimination, adult/mature, games, advertising, shopping, child abuse, plagiarism, and several others.
You can also automatically sandbox files opened from a web download, email attachment, removable drive, and/or network drive. This is great if you’re cautious about opening those types of files because they’re the primary entry points for malware.
Here are some other FortiClient features you’ll like:
- Scan on a daily, weekly, and monthly schedule
- Lock down the program with a password
- Manually check for application vulnerabilities
- AntiExploit is enabled for all your programs automatically, but you have the freedom to disable the feature on any of them
The program interface itself is easy to read and navigate, but it might be a bit too much for a novice user. There’s hardly any information regarding what each component and setting does when enabled/disabled, and a few of the features are really only useful if your computer is being managed remotely by an administrator.
Windows 10, Windows 8, and Windows 7 are supported. You can also get this free antivirus program on Linux and macOS (but with fewer features). FortiClient has a similar tool for web filtering and VPN access, too, for Chromebook, the Chrome browser, iOS, and Android.
During setup, you’re asked if you want to enable the following along with the antivirus program: SSL and IPsec VPN, FortiSandbox detection and quarantine features, and Additional Security Features which include Antivirus, Web Filtering, Single Sign On, and Application Firewall. You can turn them on during setup or later once FortiClient is fully installed.

Immunet AntiVirus
What We Like
- Tons of customizable options.
- No ads.
- Automatic updates.
- Helpful information built-in.
- Small setup file; installs fast.
What We Don't Like
- Runs on Windows only, and probably only newer editions (not XP). https://costnew944.weebly.com/blog/avast-why-doesnt-my-activation-code-work-for-mac.
Another free antivirus program that offers real time protection for Windows is from Immunet. It has a bit of an outdated interface but the software is still current, and even connects directly to the cloud for updates.
There are lots of options you can toggle on or off to customize how the software works, but you can also leave all the defaults and it will still check your computer for threats in real time.
Here are some other features you get with Immunet: Mac wont download photo app.
- Detects and removes bots, viruses, worms, Trojans, keyloggers, and spyware
- Three scan modes let you check just running processes (Flash Scan), any location of your choosing (Custom Scan), or the entire computer (Full Scan)
- Schedule any scan type daily, weekly, or monthly
- Start scans directly from Explorer on any folder or file
- A timeline shows the history of threats on the computer, to 30 days in the past. There's also an extremely detailed history of events that have happened in the program that you can filter by date, keyword, and type (such as quarantines, cleanings, blocked processes, etc.)
- Lets you run a FlashScan right after installation to check the registry and running processes for threats
- Includes a special blocking mode you can enable that prevents all programs from being installed unless they first pass a security scan
- Gaming Mode can be enabled at any time to prevent notifications from the program while watching movies or playing games.
- Automatically excludes certain folders and file types from scans, including temp folders and certain system32 folders
- Lets you manually exclude any file, folder, or threat (by its name)
- Toggle scanning on or off for archives and packed files
- Can run alongside many other antivirus programs, such as security software from Comodo, Avira, AVG, and Norton.
Immunet AntiVirus has been tested on Windows 10, Windows 8, and Windows 7, as well as Windows Server 2016/2012/2008 R2.

What We Like
- Super clean user interface that’s easy to understand.
- Unique features not found in other programs.
- Protect your email.
- Lots of options you can customize.
- Set up a scanning schedule.
What We Don't Like
- Must create a user account to activate the software.
- Several features you see in the program aren’t free.
- Can’t exclude scans by file extension.
- Slow install.
- Must renew the free license every year.
Kaspersky Free is a good choice for a free antivirus program if you want a simple program that boasts lots of features. It’s incredibly easy to use but has loads of advanced options if you care to look into them.
This free AV program is also useful if your computer is low on system resources. Kaspersky Free can automatically postpone scans and reduce display animations if the CPU runs too high, supports idle scans for when you’re away, and lets you favor performance over protection by altering the overall security level.
Another important feature to know about this program is that it includes Self-Defense, which is a function that blocks all attempts to change or delete Kaspersky’s processes, registry items, and installation files.
- Searches for rootkits and can delete malicious tools, adware, auto-dialers, and suspicious packages
- Can password protect the program to protect its settings from being changed and/or to stop it from being uninstalled or shut down
- Includes a file and web scanner as well as Network Attack Blocker, System Watcher, and Mail Anti-Virus

- Can auto-scan external drives or prompt you to scan them when they’re inserted
- Schedule quick or full scans for every day, every weekend, every weekday, weekly, or monthly
- Choose what gets scanned in a full, quick, and selective scan. Can include any of the following: system memory, startup objects, disk boot sectors, system volume information, email, all hard drives, all external devices, all network drives, any folder.
- Lets you skip items if the scan takes too long
- Speed up antivirus scans by checking only new and changed files
- Exclude files and folders from scans, and even prevent the scanning of specific threats
- Define trusted applications so that they're not scanned
Kaspersky's free antivirus program can be installed on Windows operating systems.

Avast Mac Security Free
ZoneAlarm Free Antivirus
What We Like
- Updates automatically.
- Includes a free firewall.
- Can run scheduled scans.
What We Don't Like
- Heavy on system resources.
- Slow installation.
ZoneAlarm Free Antivirus, also called ZoneAlarm Security and ZoneAlarm Free Antivirus + Firewall, is just what you think: antivirus software with a firewall tool built-in. You not only have protection against threats like spyware, viruses, Trojan horses, and bots but there are also firewall shields to block intruders from reaching your computer files.
Here are some other important features in this free antivirus tool:
- Real-time, cloud-based security updates that relies on millions of other users to stop threats quickly
- Gamer Mode can be used to block interruptions while gaming, such as scans, updates, and alerts; you can set all alerts to be automatically denied or allowed

- ProsVery good scores from independent testing labs and our hands-on tests. Network security inspector. Password manager. Many useful, security-related bonus features. Free.
- ConsPassword manager features limited. Some bonus features require separate purchase.
- Bottom LineAvast Free Antivirus combines an antivirus engine that scores very well in testing with a surprisingly extensive collection of bonus features.
You might expect that a free antivirus company would offer basic protection for free, but reserve advanced bonus features for the paid edition. However, in the real world, many of the most popular free antivirus tools pack full-scale protection along with a ton of extra features. Avast Free Antivirus gives you more than many competing commercial products. On top of excellent antivirus protection, it adds a network security scanner, a password manager, browser protection, and more. It's an amazing collection of security features, considering that this product is free.

Avast acquired rival free antivirus company AVG in 2016. Fans of both companies can rest easy; there's no plan to merge them into a single product. Both have many thousands of users worldwide, but each is strong in geographical areas where the other isn't. And the underlying antivirus engine is exactly the same in Avast and AVG AntiVirus Free, as demonstrated in my tests and independent lab tests.
This product is only free for personal use. In the past, those wishing to use Avast in a business setting had to upgrade to Avast Pro Antivirus. Currently, Avast is de-emphasizing the Pro product; it didn't get an upgrade with the rest of the product line. When you try to use a Pro-only feature in the free antivirus, the product advises that you upgrade to the Avast Internet Security suite.
During installation, Avast offers to install Google Chrome and to install the Google Toolbar in your other browsers. Unless you opt out, the toolbar makes Google your default search engine, but it doesn't take over your home page. The installer also presents a full page devoted to explaining how Avast uses your nonpersonal data, and how you can opt out if you wish.
The biggest part of Avast's main window is a slate-gray rectangle with a bit of texture, decorated with a status icon and a big button titled Run Smart Scan. A left-rail menu lets you switch from the main Status page to Protection, Privacy, or Performance. Across the bottom, you find a banner offering you a welcome gift. Unwrapping the virtual gift reveals a discounted upgrade to Avast Internet Security. If you reject the upgrade, it offers a 60-day trial. Avast really wants you to experience the suite!
One of this product's features needs special mention, because it's virtually invisible. If you install another antivirus with Avast already on the system, it automatically goes into Passive Mode. To avoid conflicts, it disables all real-time scanning and other active protection. You can still launch scans manually. There's precedent for this behavior—Microsoft Windows Defender Security Center does something similar.
Lab Scores High and Plentiful
It may seem counterintuitive, but antivirus makers typically pay for the privilege of having products included in testing by the independent labs. The companies do benefit from testing, in two ways. A high score gives the company bragging rights, while if the score is poor, the lab helps the company improve by reporting what went wrong. When the antivirus doesn't bring in any income, a company might be tempted to skip the expense of testing. Not Avast. I follow four independent testing labs that regularly release reports on their results; all four of them include both Avast and AVG.
The analysts at AV-Comparatives perform a variety of security tests, of which I follow four. Products that do well enough to pass the test receive a Standard rating, while those that show advanced features and capabilities can rate Advanced or Advanced+.
Out of the four tests, AVG and Avast both earned three Advanced+ ratings and one Advanced. That's quite good, though Bitdefender Antivirus Plus took Advanced+ in all four tests.
AV-Test Institute reports on antivirus capabilities in three areas: protection, performance, and usability. With six points possible in each category, the maximum score is 18 points. Avast got all six points for usability, meaning it didn't screw up by flagging valid programs or websites as malicious, and earned six more points for malware protection. It came close in performance, with 5.5 points. AVG precisely matched that score.
A total of 17.5 points is high enough for AV-Test to designate Avast a Top Product. Avira, Bitdefender, Kaspersky Free, and Vipre managed a perfect 18 points.
Trying to emulate real-world conditions as closely as possible, the experts at SE Labs capture drive-by downloads and other web-based attacks, relying on a replay system to hit each tested product with the exact same attack. The very best products receive AAA certification; others may be certified at the AA, A, B, or C level. Like AVG, Avast received AA certification.
Quite a few products managed AAA certification in the latest test from SE Labs. Among them were Norton, Trend Micro Antivirus+ Security, and Microsoft Windows Defender.
MRG-Effitas reports test results a bit differently from the other labs. Products that don't manage perfect or near-perfect protection simply fail. Avast passed the banking Trojans test, and achieved Level 2 certification in the all-types malware protection test, meaning that it let at least one attacker install, but remediated the problem within 24 hours. AVG also received Level 2 certification, but the lab didn't include AVG in the banking Trojans test.
Of the many antivirus products I track, 10 don't appear in results from any of the labs. AVG and Avast are among the impressive 10 featured in all four lab reports. I use an algorithm that normalizes all the results to a 10-point scale and produces an aggregate score from 0 to 10. The aggregate score of 9.4 points for these two free antivirus products is impressive; only a few have done better. Bitdefender is at the top, with 10 of 10 points, and Kaspersky runs close behind with 9.9 points. Avira Antivirus made a decent showing, with an aggregate score of 9.1 points based on results from all four labs.
Very Good Malware Protection
Malicious software from the Internet has to run the gauntlet of numerous defense layers before it can infect your PC. Avast could block all access to the malware-hosting URL, for example, or wipe out the malware payload before the download finishes—I'll discuss those malware protection layers shortly. If a file is already present on your computer, as my malware samples are, Avast assumes it must have gotten past the earlier protection layers. Like AVG, Emsisoft, McAfee, and a few others, it checks those files one more time before they execute.
To test Avast's malware-blocking chops, I opened a folder containing my current collection of malware samples and tried to launch each one. Avast blocked about three quarters of them immediately, wiping them out so fast it left Windows displaying an error message reporting that the file could not be found. It killed off most of those that managed to launch before they could fully install. I tested AVG simultaneously, with precisely the same results.
Both products detected 89 percent of the samples and scored 8.9 of 10 possible points. That's not bad, but Cylance, F-Secure Anti-Virus, Norton, and McAfee share the top spot, with 9.3 points.
When tested with my previous malware collection, Webroot SecureAnywhere AntiVirus earned a perfect 10 points. Given that the samples were different, I can't make a direct comparison with more recent tests, but a perfect score is impressive.
On detecting a file that's completely unfamiliar, Avast prevents that file from launching and sends it to Avast headquarters for analysis. Avast quite reasonably found one of my hand-coded analysis tools suspicious, so it killed the process, triggering a Windows error message. To show it wasn't really an error, Avast attached a CyberCapture tab to the error message.
Unusual activity by few other files merited deeper examination. Avast displayed a message stating, 'Hang on, this file may contain something bad,' and promising an evaluation within 15 seconds. All my hand-coded testing utilities triggered this warning; all three got a clean bill of health. AVG offers precisely the same protection for unknown and suspicious files.
The samples I use for the malware blocking test stay the same for months. To evalute each product's ability to deal with the very latest malware, I start with a feed of malware-hosting URLs supplied by MRG-Effitas. I try to launch each one in Internet Explorer, recording whether the antivirus blocked access to the URL, vaporized the malware download, or totally failed to notice anything wrong.
I test URL after URL until I've recorded data for 100 verified malware-hosting URLs, then tally the results. Avast blocked access to about 60 percent of the URLs and eliminated almost another 30 percent at the download stage, for a total of 91 percent protection; AVG turned in identical results. That's pretty good, but quite a few products have done even better. Symantec Norton AntiVirus Basic and Bitdefender share the top score, 99 percent protection, with McAfee and Trend Micro close behind at 97 percent.
Excellent Phishing Protection
Phishing websites are significantly easier to create than websites that secretively launch malware attacks. All they do is create a convincing replica of a sensitive site, perhaps a bank, or PayPal, and broadcast links to that fake site around the Web. Any user who logs in, not recognizing that the page is fake, has just given account access to the fraudsters. https://costnew944.weebly.com/blog/avast-or-sophos-for-mac. If a thousand web surfers spot the fraud and just one falls for it, that's a win for the bad guys. And when the authorities quash the fraudulent site, the fraudsters just pop up another one.
I test antiphishing using the very newest phishing sites, preferably ones that haven't yet been fully analyzed and blacklisted. I launch each probable phishing URL in four browsers. The product under test protects one of the browsers, naturally. The other three rely on protection built into Chrome, Firefox, and Internet Explorer. As with my other hands-on tests, I challenged Avast and AVG at the same time.
Any schmoe can write a phishing protection module that blocks blacklisted sites. The best products use real-time analysis to identify frauds that are too new for the blacklists. Avast clearly has this capability; the company touts its enhanced real-time phishing detection technologies. In testing, it proved quite effective.
With an impressive 98 percent detection of phishing frauds, Avast joins an elite group with top scores in this test. Trend Micro, ZoneAlarm, and AVG also managed 98 percent. Bitdefender weighed in with 99 percent, while both Kaspersky and McAfee AntiVirus Plus managed a perfect 100 percent detection.
Scan Choices
If you just click the big button in the middle of Avast's Status screen, it runs a Smart Scan. Its features overlap the Computer Scan in AVG, in that it checks browser add-ons, scans for active malware, and identifies performance issues. But Avast also checks for network security problems, flags software that lacks security patches, and warns about weak passwords. The scan finished in less than ten minutes on my test system. It found several vulnerable apps and, at my request, updated them. It flagged a network problem; more about the network scan below. And, like AVG, it found performance problems but wouldn't fix them unless I updated to the premium cleanup product.
Clicking Scan on the Protection page gets you more choices. The Full Virus Scan took a bit over two hours on my standard clean test system. That's about the same time as AVG's Deep Scan took, and it's well over twice the current average of 50 minutes. I recommend running that full scan at least once soon after installation, to root out any existing malware. After that, the product's real-time protection layers should fend off any further attacks.
Like AVG, Avast offers a boot time scan, designed to eliminate pernicious and persistent malware that resists normal cleanup. Because the scan runs before Windows boots up, the Windows-based malware doesn't have any chance to defend itself. AVG's boot scan requires installation on first use, while Avast's is ready to go out of the box. With either product, you should set aside plenty of time for the scan. Note that Bitdefender's Rescue Mode reboots in a non-Windows operating system for even more power against Windows-centered malware.
Wi-Fi Inspector
Avast was one of the first security products to add a network security scanner to its product line. Despite 'Wi-Fi' in its name, the Wi-Fi Inspector can report on all the devices connected to any network, wired or wireless, and flag devices with security problems.
On my test system, the scan ran quickly and displayed my devices in a series of concentric rings, with the router at the center and the devices that connected most recently in the inner circles. Avast reported a problem with the Wi-Fi router, flagging its password as weak. When I repeated the test on a wired network, it warned that the HTTPS port on the main router was visible from the Internet (a necessary configuration setting for my Network Attached Storage backup device).
Avast does its best to identify each device by name and type, but it can't always get that information. If you have some network skills, you may be able to identify a device from its IP address and MAC address. You can change the type of any device to any of five dozen choices, among them security sensor, head mounted display, and hand-held gaming console. You can also change the name to something more recognizable than, say, Unknown70259bb1f4e. And Avast remembers your changes for future scans.
Avira users can install Avira Home Guard from the main Avira launcher; it works very much like the Wi-Fi Inspector. Bitdefender Home Scanner is another similar (and free) network security scanner, one that goes into more depth about possible security problems.
Simple Password Manager
Password management is an unexpected feature for a free antivirus, though Avira offers Avira Password Manager as a companion to its free product. Avast Password Manager handles all the basic functions, and does them well, but that's as far as it goes.
To get started, you activate the password manager as an extension in Chrome and Firefox. Next, you create a master password that will protect all your website passwords. Avast no longer offers advice on the construction of a strong password, so be sure to choose something that you can remember, but that nobody else would guess.
In either supported browser, Avast offers to save the login credentials you enter for secure sites. When you revisit a website, it fills in your saved credentials. If you have multiple accounts on the site, you can click a little key icon in the username field to get a menu of all your choices. And it does handle Gmail and other two-page logins.
With many password managers, clicking the toolbar icon gets a menu of logins. Avast works differently. If you've saved one or more sets of credentials for the current site, it displays those in a popup window. If that's not what you want, there's a link to open the app. From the same window, you can invoke the password generator, which creates 15-character passwords using letters and digits (but not punctuation) by default.
In the app, you can edit your saved passwords to give them a friendly name. You can also add Secure Notes and Credit Card details. When you visit a web form that asks for credit card data, you click the Avast key icon to fill in the card of your choice. In addition, you can sync password data to Avast's iOS or Android apps.
Avast isn't much help if you're switching from another password manager. It can import passwords stored in Chrome or Firefox, but that's it. There's no import from competing products, or even from plain CSV files. In addition, the password manager no longer reports on weak or duplicate passwords.
Some password management features hide behind a paywall, with a list price of $1.58 per month, currently discounted to $0.99 per month. Paying customers get tech support on a 24/7 basis, receive an immediate alert on detection of a password leak, and can log into the mobile apps with a fingerprint. These aren't very impressive as premium features. Truly advanced features like two-factor authentication and secure password sharing just don't appear. If you want more from a password manager, you're probably better off adding a separate free password manager.
Avast Online Security
Like the password manager, the Avast Online Security extension installs in Chrome and Firefox. If you don't see it, dig into settings; I found that I had to enable the extension manually. Note that the similar AVG Web TuneUp is no longer installed as part of AVG's free antivirus.
Online Security marks up your search results in popular search portals. Green means all clear, red means stay away, and gray means the site hasn't yet been analyzed. You can click the toolbar icon to give a simple thumbs-up or down to the current page.
If Online Security detects any advertising trackers or other trackers on the current site, it displays how many it found as a number overlaid on the icon. Clicking the icon gets you a summary of found social media, advertising, and web analytics trackers. You can dig in for details and block some or all trackers on the current site or automatically block all trackers on all sites.
You won't easily see the SiteCorrect feature in action. It kicks in when you misspell a popular domain name, steering you away from typosquatting sites that try to capture your clicks.
Online Security also watches out for dangerous and fraudulent websites. However, this feature is less important now that Avast filters out such sites before they even reach the browser.
Bonus and Premium Features
Software is created by humans, and hence imperfect. White hat and black hat hackers are constantly finding security holes, and security companies strive to patch them as soon as possible. If you fail to apply security updates, you leave your computer open to attacks that exploit those holes. Avast's Software Updater scans your computer and reports any out-of-date software it finds. You can click a link to find out what changed in each product, or click a button to install the updates. If you try to turn on automatic updates, you learn that this is a feature of the paid security suite.
Avast's Driver Updater promises to reduce crashes by updating old and broken drivers. It installs the first time you try to use it. On my test system, it found exactly one outdated driver. I clicked to replace the antique driver…and ran into a paywall, hidden behind several layers of other windows. Boo!
Avast Cleanup Premium is a bit more honest; you know right away that it's a premium-only feature. Oh, it happily scans your system for performance problems, but if you want to do anything about those problems, you must shell out for a subscription.
At least you don't have to pay for Do Not Disturb mode. This kind of feature is becoming very common in antivirus products. When it's active, the antivirus postpones scheduled scans and suspends all but the most critical notifications. Many products automatically switch to Do Not Disturb when you launch a full-screen program. As with the similar feature in AVG, Avast requires that you list the programs for which you want Do Not Disturb mode active.
Like the similar feature in AVG, the SafePrice add-on helps you find the best prices when you're shopping online. Just click its toolbar icon to see what details it found. It also offers coupons, when available.
On the Privacy page you'll find a link for Avast SecureLine VPN. This one isn't precisely a premium feature, in that it lets you use the VPN in trial mode for 60 days. But after that you'll have to pony up $1.99 per month.
Have you ever noticed those ads that seem to follow you from site to site? Advertisers track your web surfing and preferences, so you can't escape. Or can you? AntiTrack Premium apparently supplements the Do Not Track protection found in Avast Online Security. Unlike most of the other premium features, you don't even get a peek at what this one does until you subscribe.
Pro-Only Features
You've seen that some apparent features of the free antivirus aren't free; when you try to use them, you get a prompt to pay for an additional subscription. For quite a few other features, there's no confusion at all. The component's icon on the Protection or Privacy page displays a lock icon, and clicking any of those icons instructs you to update to Avast Internet Security.
On the Protection page, locked icons include: Firewall, to keep hackers out of your system; Sandbox, to run suspicious files without risk; Real Site, website confirmation beyond detection of phishing frauds; and Ransomware Shield. This last item deserves some explanation. Avast's regular behavior-based detection should catch ransomware just as it does other types of malware. On the off-chance it might slip up, Ransomware Shield bans unauthorized modification of your documents and other sensitive files.
There are also several Pro-only privacy features. You must upgrade to get the secure deletion Data Shredder (AVG gives you this feature at the free level). The Sensitive Data Shield scans your documents for sensitive data that could be vulnerable to exfiltration, and helps you protect it. And the Webcam Shield offers a degree of spyware protection by limiting webcam use to known, trusted programs. If these features seem intriguing, you may want to consider Avast's full security suite.
An Excellent Free Antivirus
Avast Free Antivirus offers antivirus protection that earns good scores in my hands-on tests and very good scores from the independent testing labs. As for bonus features, it offers much more than many competing commercial products. Yes, some of the bonus features require a separate purchase, but that's a relatively minor point. Avast remains an Editors' Choice product for free antivirus.
The base antivirus engine in AVG Antivirus Free is exactly the same as Avast's, but AVG just doesn't offer the wealth of additional security features that you get with Avast. Go ahead and try it if you like, but we're no longer calling it an Editors' Choice.
Kaspersky Free is our other Editor's Choice free antivirus. Where Avast gets very good ratings from the four independent labs that I follow, Kaspersky gets the very best marks. It comes with a bandwidth-limited VPN, but not many other frills. The key with Kaspersky is getting antivirus protection loved by the labs without any cost.
Avast Free Antivirus
Bottom Line: Avast Free Antivirus combines an antivirus engine that scores very well in testing with a surprisingly extensive collection of bonus features.
