Best Free Antivirus 2017 For Mac

Malware, Spyware, and Adware Protection

Avg antivirus free 2017 free download - AVG AntiVirus for Mac, and many more programs. Free antivirus software from Avira, Avg, Avg, Mcafee - is it any good? There are many companies offering free antivirus software like Avira, Avg, Avast, Mcafee and Norton but are they any good? Antivirus software is widely available on the internet today with countless antivirus software provides to choose from.

Summer is winding down. Before you know it, kids will head off to school and come back with homework, notes from the teachers, and…malware? Quite possibly. You've protected your own PCs and laptops, but did you make sure to install antivirus protection on your child's laptop? If not, your kid could pick up more than a head cold at school. Viruses, Trojans, ransomware, or what-have-you, any kind of malware does well in a network populated by youths who aren't thinking about security. We've tested and rated more than 40 antivirus tools so you can pick the right one to protect you and your family from the evil side of the internet.

We call it antivirus, but in truth it's unlikely you'll get hit with an actual computer virus. Malware these days is about making money, and there's no easy way to cash in on spreading a virus. Ransomware and>field we've named four Editors' Choice products.

Some nonstandard commercial antivirus utilities proved effective enough to earn an excellent four-star rating alongside their more traditional counterparts. VoodooSoft VoodooShield bases its protection on suppressing all unknown programs while the computer is in a vulnerable state, such as when it's connected to the internet, and also acts to detect known malware. The Kure resets the computer to a known safe state on every reboot, thereby eliminating any malware. If you have malware, one of the ten products in the chart above should take care of the problem.

You may notice that one product in the chart earned just 3.5 stars. The chart had room for one more, and of the seven 3.5-star products, the labs only pay attention to F-Secure and G Data. F-Secure has the added fillip of costing the same for three licenses as most products charge for just one, so it made its way into the chart. The blurbs at the bottom of this article include every commercial antivirus that earned 3.5 stars or better.

These commercial products offer protection beyond the antivirus built into Windows 10; the best free antivirus utilities also offer more. However, Microsoft Windows Defender Security Center is looking better and better lately, with some very good scores from independent testing labs. The combination of good lab scores and a great score in our hands-on malware protection test was enough to bring it up to 3.5 stars.

Listen to the Labs

We take the results reported by independent antivirus testing labs very seriously. The simple fact that a particular vendor's product shows up in the results is a vote of confidence, of sorts. It means the lab considered the product significant, and the vendor felt the cost of testing was worthwhile. Of course, getting good scores in the tests is also important.

We follow four labs that regularly release detailed reports: SE Labs, AV-Test Institute, MRG-Effitas, and AV-Comparatives. We also note whether vendors have contracted with ICSA Labs and West Coast labs for certification. We've devised a system for aggregating their results to yield a rating from 0 to 10.

We Test Malware, Spyware, and Adware Defenses

We also subject every product to our own hands-on test of malware protection, in part to get a feeling for how the product works. Depending on how thoroughly the product prevents malware installation, it can earn up to 10 points for malware protection.

Our malware protection test necessarily uses the same set of samples for months. To check a product's handling of brand-new malware, we test each product using 100 extremely new malware-hosting URLs supplied by MRG-Effitas, noting what percentage of them it blocked. Products get equal credit for preventing all access to the malicious URL and for wiping out the malware during download.

Some products earn absolutely stellar ratings from the independent labs, yet don't fare as well in our hands-on tests. In such cases, we defer to the labs, as they bring significantly greater resources to their testing. Want to know more? You can dig in for a detailed description of how we test security software.

Multilayered Malware Protection

Antivirus products distinguish themselves by going beyond the basics of on-demand scanning and real-time malware protection. Some rate URLs that you visit or that show up in search results, using a red-yellow-green color-coding system. Some actively block processes on your system from connecting with known malware-hosting URLs or with fraudulent (phishing) pages.

Software has flaws, and sometimes those flaws affect your security. Prudent users keep Windows and all programs patched, fixing those flaws as soon as possible. The vulnerability scan offered by some antivirus products can verify that all necessary patches are present, and even apply any that are missing.

Spyware comes in many forms, from hidden programs that log your every keystroke to Trojans that masquerade as valid programs while mining your personal data. Any antivirus should handle spyware, along with all other types of malware, but some include specialized components devoted to spyware protection.

You expect an antivirus to identify and eliminate bad programs, and to leave good programs alone. What about unknowns, programs it can't identify as good or bad? Behavior-based detection can, in theory, protect you against malware that's so new researchers have never encountered it. However, this isn't always an unmixed blessing. It's not uncommon for behavioral detection systems to flag many innocuous behaviors performed by legitimate programs.

Whitelisting is another approach to the problem of unknown programs. A whitelist-based security system only allows known good programs to run. Unknowns are banned. This mode doesn't suit all situations, but it can be useful. Sandboxing lets unknown programs run, but it isolates them from full access to your system, so they can't do permanent harm. These various added layers serve to enhance your protection against malware.

Firewalls, Ransomware Protection, and More

Firewalls and spam filtering aren't common antivirus features, but some of our top products include them as bonus features. In fact, some of these antivirus products are more feature-packed than certain products sold as security suites.

Among the other bonus features you'll find are secure browsers for financial transactions, secure deletion of sensitive files, wiping traces of computer and browsing history, credit monitoring, virtual keyboard to foil keyloggers, cross-platform protection, and more. You'll even find products that enhance their automatic malware protection with the expertise of human security technicians. And of course we've already mentioned sandboxing, vulnerability scanning, and application whitelisting.

We're seeing more and more antivirus products adding modules specifically designed for ransomware protection. Some work by preventing unauthorized changes to protected files. Others keep watch for suspicious behaviors that suggest malware. Some even aim to reverse the damage. Given the growth of this scourge, any added protection is beneficial.

Beyond Antivirus: VPN

Your antivirus utility works in the background to keep out any faint possibility of infestation by malware, but its abilities don't extend beyond the bounds of your computer. When you connect to the wild and wooly internet, you risk the possibility that your data could be compromised in transit. Sticking to HTTPS websites when possible can help, but for full protection of your data in transit you should install a virtual private network, or VPN. This component is important enough that we're starting to see it as a bonus feature in some antivirus tools.

What's the Best Malware Protection?

Which antivirus should you choose? You have a wealth of options. Kaspersky Anti-Virus and Bitdefender Antivirus Plus routinely take perfect or near-perfect scores from the independent antivirus testing labs. A single subscription for McAfee AntiVirus Plus lets you install protection on all of your Windows, Android, Mac OS, and iOS devices. And its unusual behavior-based detection technology means Webroot SecureAnywhere Antivirus is the tiniest antivirus around. We've named these four Editors' Choice for commercial antivirus, but they're not the only products worth consideration. Read the reviews of our top-rated products, and then make your own decision.

Note that we have reviewed many more antivirus utilities than we could include in the chart of top products. If your favorite software isn't listed there, chances are we did review it. The blurbs below include every product that managed 3.5 stars or better. All the utilities listed in this feature are Windows antivirus apps. If you're a macOS user, don't despair, however; PCMag has a separate roundup dedicated solely to the best Mac antivirus software.

Editors' Note: We are aware of the allegations of Kaspersky Labs' inappropriate ties to the Russian government. Until we see some actual proof of these allegations, we will treat them as unproven, and continue to recommend Kaspersky's security products as long as their performance continues to merit our endorsement.

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.

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.

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.

of 11

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

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.

• 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.

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.

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

• 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).

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:

• 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

Kaspersky Free

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.

10 Best Antivirus Software 2017

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.

• 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
