One nasty virus could expose your financial information or stop your computer from working at all. What you need is the best antivirus software possible on your computer. Fortunately, some of the best are also completely free! Many companies offer free versions of their popular antivirus programs for home users. My favorites are,, and (in that order) but be sure to look through the alphabetical list below to find the best free antivirus for you.

Important: I've included no trial or shareware antivirus programs in this list. These are the best antivirus programs that are completely free and work similarly to, or better than, expensive programs from companies like Norton and McAfee. See my list if you're interested in free antivirus tools without constant virus protection or my list if you're interested in a free online-based antivirus scan of a file.

Adaware Antivirus. Lavasoft's Adaware Antivirus Free program is different than the 'Ad-Aware' you may already be familiar with. This program is a true, always-on, completely free antivirus program. Adaware Antivirus Free supports Windows 10, 8, 7, Vista, and XP. If my list was anything other than alphabetical, Adaware Antivirus Free probably wouldn't head up the pack, mainly because email scanning isn't supported. However, if you love Lavasoft's other free products, Adaware Antivirus Free is a pretty solid choice.

Amiti Antivirus. © NETGATE Technologies s.r.o.

Amiti Antivirus is a free antivirus program that includes heuristic scanning and supports 4 different scan types, including one that can check for viruses that are currently running in memory. Amiti Antivirus can be used with Windows 10, 8, 7, Vista, and XP. I really like how easy Amiti Antivirus is to use. All the settings and options are organized on the left side of the program in their respective areas without being overly cluttered. There's also a tool included in Amiti Antivirus that can be used to quickly clean temporary system and Internet Explorer files to free up disk space.

Free Antivirus. © AVAST Software AVAST Software's avast! Free Antivirus most certainly deserves to be on any list of the best free antivirus programs. Free Antivirus has fully functioning antivirus and antispyware engines protecting your PC from threats from the internet, your files, emails, and even instant messages. One big reason I included avast!

Free Antivirus as a best free antivirus program is because of its 'heuristics engine' which can detect previously unknown viruses and other malware. I also like the fact that AVAST has been making this antivirus product since 1988 and is often cited as the most installed antivirus product. Free Antivirus supports Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP. AVG AntiVirus Free. © AVG Technologies AntiVirus Free from AVG is one of the best free antivirus software tools available and is probably my personal favorite. AVG AntiVirus Free is a full-fledged antivirus and antispyware tool, includes an email scanner, link scanner, scheduled scanning options, automatic updates, and more.

There is no need to pay for an antivirus program when one this good is just a download away. The huge number of premium features, ​the frequency of updating, and install-it-and-forget-it aspect of AVG's AntiVirus Free really do make it one of the best of the best free antivirus programs available today. AVG AntiVirus Free works on Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP.

Avira Free Antivirus. © Avira Operations Avira Free Antivirus protects you from viruses, Trojans, worms, spyware, adware, and various other kinds of malware, making it a fully functional antimalware tool and one of the best free antivirus programs.

The scope of malware that Avira Free Antivirus can keep you safe from is alone enough to make it one of the best free antivirus software programs but the heuristics and ease of use add to its value too. The only things I didn't like about Avira Free Antivirus was the configuration you have to complete after installation which might be intimidating if you're a computer novice. Avira Free Antivirus works on Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP. Avira can also be used on a Mac and Linux computer. Bitdefender Antivirus Free Edition. © Bitdefender Bitdefender Antivirus Free Edition is on par with any of the arguably better-known free antivirus programs ​on my list. Bitdefender Antivirus Free Edition is incredibly easy to setup and configure, uses very little system resources (it won't slow down your computer), and doesn't constantly suggest that you upgrade to their premium offerings.

The sheer simplicity of Bitdefender Antivirus Free Edition, both during installation and use, make it, in my opinion, one of the better of the best free antivirus programs. Antivirus Free Edition by Bitdefender fully supports Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP.

Baidu Antivirus 2015 v5.4.3. © Baidu, Inc. Baidu Antivirus 2015 is lightweight and fights malware via its cloud-based virus database. It has an anti-hacker firewall, anti-phishing protection, anti-keylogger, webcam protection, automatic download protection, quarantine sandbox, and other extremely useful features.

It automatically updates, scans USB devices and the Windows registry, can have its settings password protected, has a built-in cloud file scanner to upload suspicious files to Baidu to be scanned, and supports several other useful tools like a traffic monitor and private browser tool. Overall, Badiu Antivirus 2015 ran quickly, using little system resources, and functioned just as good as the other antivirus programs in this list.

Baidu Antivirus 2015 works in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP. Comodo Antivirus.

Comodo Antivirus from Comodo Security Solutions is another excellent program, easily one of the best free antivirus options out there. Comodo Antivirus protects you from several threat sources, just as most of the other free antivirus programs on this list do. Comodo Antivirus ranks as a best free antivirus solution almost solely because of its Defense+ technology that, by default, assumes unknown files are threats instead of safe. That sounds like it might cause problems but Comodo Antivirus utilizes some other technologies to make the whole process silent but still very effective.

Comodo Antivirus officially supports Windows 10, Windows 8, Windows 7 and Windows Vista. FortiClient is an antivirus, web filtering, firewall, parental control, optimization, (and then some) program that's powerful enough for a business to use.

It's more accurately referred to as a 'threat management' tool. While that might all sound really complicated, especially considering that you probably only have one computer you're worried about, FortiClient is really easy to setup, automatically updates its virus definition files, does a full system scan once per week, and much more, all without you ever having to worry about it. FortiClient supports Windows XP and newer Windows operating systems, which includes Windows 10, Windows 8, Windows 7, and Windows Vista. It can also run on macOS, Chromebook, and mobile devices. Immunet is a unique, cloud-based antivirus program that's a bit like Panda Protection below. Immunet protects your computer from bots, worms, viruses, Trojans, keyloggers, and spyware. I think Immunet is one of the best free antivirus programs for several reasons: you never have to update it, it has completely free telephone based support, and it can be run alongside some of the other best free antivirus tools in this list, increasing your overall protection.

Immunet can run on Windows 10 down through Windows XP.
