Best FREE Antivirus

Protecting your computer from viruses is important. 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. Luckily, some of the best antivirus software is completely free!
So why are some of the very best antivirus programs free? Many popular antivirus companies offer free versions of their programs for home users while offering versions with more advanced features as an upgrade option for professional and business users.
Important: There are no "on-demand only" (without constant virus protection), trial, or shareware antivirus programs in this list. These are the best antivirus programs that are completely free and work similarly to expensive programs from companies like Norton and McAfee.

1. AVG Anti-Virus Free

Anti-Virus Free from AVG is the best free antivirus software available. AVG Anti-Virus 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 the best free antivirus software in the world is just a download away.
AVG Anti-Virus Free works on Windows 7, Windows Vista, Windows XP and Windows 2000.
The huge number of premium features, frequency of updating, and install-it-and-forget-it aspect of AVG's Anti-Virus Free really do make it the best of the best free antivirus programs available today.

2. avast! Free Antivirus

AVAST Software's avast! Free Antivirus most certainly deserves to be on any list of the best free antivirus programs. avast! Free Antivirus has fully functioning antivirus and antispyware engines protecting your PC from threats from the Internet, your files, emails, and even instant messages.
avast! Free Antivirus supports Windows 7, Windows Vista, Windows XP and Windows 2000.
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.
Tip: During the avast! installation, you're asked to install the free Google Chrome browser. It's not required so if you're not interested just uncheck the box. Also, you are required to register avast! to use it more than 30 days but registration is free and pretty simple. You'll also have to reregister once per year - again, for free.

3. Microsoft Security Essentials

Security Essentials from Microsoft is definitely one of the best free antivirus programs available right now. Microsoft is relatively new to the antivirus game but don't let that scare you - Security Essentials is a fantastic antivirus program that protects you from all sorts of malware, updates automatically, and is incredibly easy to use.
Microsoft Security Essentials supports Windows 7, Windows Vista and Windows XP.
Two of the biggest reasons I added Microsoft Security Essentials to this list of the best free antivirus software is because it's directly from Microsoft and also because it's very easy to see if you're computer is secure from threats: if the icon next to your clock is green, you're in good; if it's red, something is wrong.

4. Comodo Antivirus

Comodo Antivirus from Comodo Security Solutions is another excellent program, easily one of the best free antivirus options out there. As of this writing, Comodo Antivirus bills itself as the "Best Antivirus on the Market. Guaranteed." due to its proprietary Defense+ technology. Comodo Antivirus also protects you from several threat sources, just as most of the other best free antivirus programs on this list do.
Comodo Antivirus works on Windows 7, Windows Vista and Windows XP.
Comodo Antivirus is easily one of the best free antivirus solutions 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.

5. Avira AntiVir Personal

Avira AntiVir Personal protects you from viruses, Trojans, worms, spyware, adware, and various other kinds of malware, making it a fully functional antimalware tool and certainly one of the best free antivirus programs.
Avira AntiVir Personal works on Windows 7, Windows Vista, Windows XP and Windows 2000. Avira also makes a version of AntiVir Personal for UNIX.
The scope of malware that Avira AntiVir Personal 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 AntiVir Personal was the configuration you have to complete after installation which might be difficult if you're a computer novice.
Tip: You're asked to register during the Avira AntiVir Personal installation but it's optional. Just uncheck the box and continue with the install.

6. Panda Cloud Antivirus

Panda Cloud Antivirus protects you from several kinds of malware threats - viruses, worms, Trojans, adware, and more - just like all the other free antivirus programs in this list.
What makes Panda Cloud Antivirus one of the best free antivirus programs is that it does its job from "the cloud" meaning the hard antivirus work that typically slows down a computer is done on computers elsewhere on the Internet, freeing up your computer to work like it should and protecting you from malware even better.
Panda Cloud Antivirus supports Windows 7, Windows Vista and Windows XP.
Tip: Panda Cloud Antivirus tries to install a toolbar and set Yahoo! as your browser's home page during the installation process so uncheck the boxes before continuing if you don't want them. Neither are required to use Panda Cloud Antivirus.

7. Immunet Protect FREE

Immunet Protect FREE is a unique, cloud-based antivirus program, much like Panda Cloud Antivirus. Immunet Protect FREE protects your computer from bots, worms, viruses, Trojans, keyloggers, and spyware.
Immunet Protect FREE works on Windows 7, Windows Vista and Windows XP. You must also be connected to the Internet at all times.
I think Protect FREE from 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 like AVG Anti-Virus Free, Microsoft Security Essentials, and avast! Free Antivirus, increasing your overall protection!

8. digital-defender Antivirus

digital-defender Antivirus isn't a popular antivirus program but it should be. It's certainly one of the best free antivirus software programs you'll find. It's a full antivirus and antispyware program and updates on a daily basis.
digital-defender Antivirus supports Windows 7, Windows Vista and Windows XP.
The relatively small installation size, daily virus definition updates, and full antispyware features make digital-defender Antivirus one of the better tools in my collection of the best free antivirus programs.

9. PC Tools AntiVirus Free

PC Tools AntiVirus Free offers basic protection against viruses and other malware. While not my favorite, AntiVirus Free is still one of the best free antivirus programs you'll find.
PC Tools AntiVirus Free works on Windows 7, Windows Vista and Windows XP.
The biggest problems I have with PC Tools AntiVirus Free are the reminders throughout the program that there's a not-so-free version that you should upgrade to. To be fair, you probably won't notice it since the program runs silently in the background to protect you from viruses. I probably find it annoying because most of the features available in the upgrade are included for free in some of the higher rated best free antivirus programs above.


  1. hey thanks for this, I rarely protect my computer, but now I will download the free software and start scanning it for viruses and malware!

  2. Wow, I always though virus protection was useless.

  3. Nice list, very helpful for people who need a quick and free form of protection =D Any other free wares you suggest?

  4. Avast! is really awesome, nice post :)

  5. I switched from AVG to Avast, I don't remember the reason why, but I've been using Avast ever since.

  6. Those seem helpful. I'm tired of having to manually remove viruses.


  7. Thanks for this.
    Personally, I use Norton 360
    It works really well, although I only got it because I didn't want to take any chances with free software.

  8. Your explanations are very thorough. I honestly know nothing about computers, so both posts so far have been highly informative.

  9. thanks, my anti virus is about to expire thanks for your advice

  10. I use AVG, its pretty great. +followed

  11. I use AVG on my PC back home but I use McAfee on my Mac, but only because my university provided it for free. Great post! Followed.

  12. Yes AVG, best antivirus for sure. Good to see a nice list of the rest though, never know when you'll need to use a different one for some reason.

  13. Thanks for the headsup man, I need to go download it. Followed!

  14. I mostly use linux/mac but i have AVG on my windows box

  15. you have to be careful with the free stuff, but this was a helpful guide. thanks for posting!

  16. I use AVG free here. Works great

  17. I've used most of those. The odd ones out would be Panda Cloud and Immunet.

    Personally I prefer AVAST, though.

  18. Thanks for the tip

  19. You work in security for a living ?

  20. thank you!
    was very usefull for me! :D

  21. Im using Avast myself, at least on my laptop. On my main PC, I don't use anti-virus software. Dont really think its needed.

  22. Good thing I started using Ubuntu. Don't need any antivirus programs here - only common sense :D
    I did use AVG back when I was still using windows daily.

  23. I've been using Avast but its starting to piss me off. I think I'm going to switch to AVG soon.

  24. I've only found virus protection useful in extreme cases. Almost any problems I have had I've solved myself, and virus protection software has only hindered me solving the solution myself. But you should ALWAYS have some anti-virus programs just in case.

  25. i got Eset Nod 32 and avast pro and i still managed to get viruses

  26. I use norton and it works very well, but I'm always in the market for something better.

  27. you forgot malware bytes that shit is LEGIT!!!!!

  28. Definitely agree with you on the AVG! It has been helping my computer since I got it

  29. I use Avira Antivir personally, love it.

  30. Sweet, I use #1 and #2 on your list, guess I'm doing alright.
