  1. Ravi Gupta

    Antitvir has blown it with their latest release. AVG has been lacking in both detections and resource friendliness. That leaves just MSE and avast!. I prefer MSE on 64-bit systems and avast! on 32-bit systems.

  2. wonder-boy

    I use MSE and I’m happy using it.

  3. Cosmin Tataru

    I install Avast free on Windows XP customer PC’s and always MSE on genuine Vista and/or Windows 7 PC’s.

  4. trm96

    I used to use AVG but now I use MSE. I am shocked Microsoft made such a great AV and for free! I have installed MSE on all my Windows boxes (XP, Vista, Win 7).

  5. MSE works great on Windows 7 64bit.

  6. James

    I have used MSE but have switched back to Avast because it seems to update definitions. I have to check Windows Update to update MSE definitions. It could take up to 24 hours for it to update and install automatically.

  7. Mr. Spark

    MSE is great on its stage …. but I would also like to suggest you to go for Panda Cloud Antivirus.

  8. One that definitely needs to be added to the list is Comodo. I’ve been using it about 8 months and it works very well. It’s easy to use but still has very advanced features for the power user. It also provides internet firewall capabilities a’la Zone Alarm. I’ve also taken to using their free Comodo Backup software.

    I’ve used the others too. I used AVG for a long time but ditched it because it was too much of a cpu hog for my liking. Even coming out of sleep mode it insisted on chewing up cpu for several minutes before calming down.

    MSE was a similar resource hog. It seemed to just chew up lots of memory, leak handles, and just not function very well.

    My only negative comment about Comodo is that it tends to be a little too aggressive about reporting false positives. You have to add exceptions for things like the tightvnc installer binary (I keep it in my dropbox), that sort of thing.

  9. Gumilar

    I’m Indonesian
    The Best Is Kaspersky 7 & 2010
    Other Than That There Is No Good
    Other Than That Suck
    AVG Avast Avira
    Usually Only Remove Viruses
    Then I Could Too If Just Remove The Virus

  10. FostWare

    I’m surprised no-one mentions FortiClient which is free, can be used in commercial environments, and comes from a company that does corporate filtering routers and firewall.

  11. Software Collection

    Avira 10 is the newest version and good for protection

  12. I have used Microsoft Security Essentials and Panda Cloud Antivirus Free and have been very pleased with both. I am now commited to Kaspersky Internet Security because it provides hacker and banner protecton. Neither MSE nor Panda can defend well against web-attacks. But they will do for a casual user.

  13. TestGOTD75

    Out of free antiviruses, Avast 5 and Microsoft Security Essentials are the best.

    Out of paid antiviruses, Kaspersky (KIS 2011) and BitDefender (soon 2011 will be released) are the best.

  14. MSE for me 😉
    Install and never worry.

  15. Veleno1973

    Gli antivirus free non servono.Per chi usa internet e scarica di tutto l antivirus deve essere in ver. PRO.Un buon virus disabilita e rimuove gli antivirus free.

  16. Tealfloss

    Panda the best

  17. MSE is useless!! It rated very low on recent tests, it’s just a dummy -_-

  18. melek eddine Sahli

    panda cloud antivirus has a good detection but it slowed down my pc

  19. Will J

    AVG? They don’t have a free version any more. A time-limited “free trial” doesn’t count to me.

  20. jjstccean

    Totally AGREE!

  21. jorge correa

    Long time no comments… I’m using Avira Free Antivirus latest version. Avira has been in the top 5 best antivirus with excellent detection & removal rates.I have been using it for the last year with no issues what so ever. You will get a pop-up add once in awhile but it’s not a big issue. It’s the price you pay for free protection and Avira FREE is as good, and in some cases, better than paid software. Give it a try and enjoy …

  22. I have used Avast for almost one year. A few days back one of my friend suggested me about
    the antivirus protection services of AskPCExperts and trust me there services
    are really very good and at a reasonable price.

  23. I Used Complete Free Comodo Antivirus for Windows 7 – Download Here:

  24. Robb Thurston

    Dear Anand Khanse, I must say I receive your comments and blogs very gratefully and have used many of your offerings on my Win. 7. I do suggest, however, that, sadly, PC Tools is being eliminated by Symantec, either totally or in part. I really like PC Tools and miss it . Please think and ask yourself, is there any point in referring to an extinct application/extension/add-on? With a whole lot of respect and pleasure in your company!!!

  25. Thanks. I have removed it. 🙂

  26. Robb Thurston

    I hope to receive some reply here, altho it is slightly off topic. Here goes, and redirect me if so required. Subject:meganet-decentralized-internet. Do you or any of your acquaintances comment on meganet? Advise.

  27. SteveDitkosQuestion

    Sure they do. I use AVG AntiVirus Free Edition 2015. Look again.

  28. SERG

    and NANO Antivirus!

  29. Harry

    Spybot search and destroy has a free version (besides apaid version) it protects the PC very well if used on a regular basis with many features. Also Malwarebites has a free version

  30. Om

    1) Never trust anyone/thing;
    2) The more it differ from standard (default/vendor), the better/safer.

    So I prefer Comodo + SuRun + SandBoxIE + OpenVPN + modified configs/group policies
