What is the best antivirus program for Windows 7?

I’m very frustrated. Used Comodo long time. I think it’s good, but I don’t see it anywhere near the top antiviruses.

Now I installed BitDefender Total Security. I’m thinking of Microsoft Security Essentials. In CNET’s top downloaded is Avast and AVG. How to choose the best one?

For a long time I’m not in peace with antiviruses. I also use Advanced System Care. I think it speeds up my PC.

I have some problems. I’ve installed AllShare Play and Mega Cloud Backup and then uninstalled, but they don’t want to disappear from my PC.

What do we need for our Windows 7 PCs? Mine is Dell Inspiron N5010 i3.

      As Yashodhan Bhatt says...
      Kaspersky Internet Security 2013 IMHO is the best. Once you have used it you won't use anything else. It is reasonably priced and it works.

    It is all about the personal likings..... I prefer Norton to Avast...Some prefer Avast some AVG...... All the antivirus are good until your system is not infected....once infected only then the best one rises..........

    Just try Kaspersky for once and you'll never buy any other ever!

    AVG is listed as the top free program, in fact, best program overall. See list here: http://freebies.about.com/od/computerfreebies/tp/best-free-antivirus.htm

    I prefer Microsoft Essentials for my personal computer (I download A LOT so it keeps me quite safe) It updates on it's own and if the symbol is green, you're good to go, red if there is something you need to deal with. I was really surprised that Microsoft put out a good program to be honest, but hey Win7 is good too so they were on the right track (until win8. heh.)

    I also have backups for specific things. I use Malewarebytes for really nasty stuff, and as a backup because no antivirus is perfect. I also have CCleaner to deal with registry stuff and halting problematic programs.

    in my opinion you may download register and use avast because its free,lightweight and less resource hungry but PERFORMED VERY GOOD THAN ALL OTHER SECURITY SUITS WHEN I TESTED iT.avast will clean your system and will not allow malwares to enter your system.i am using it since 2010

    If you can buy Kaspersky as its really good and I have been using it for more than three years without any virus or malware issues
    or you can also use free Microsoft Security Essentials (Windows Defender) and its free!!

  18. Paolo Maffezzoli
    November 13, 2012 at 6:36 pm

    I would recommend Avast Internet Security or in alternative Avira. Take a look also the Kaspersky Internet Security 2013, maybe you can install the trial version and evaluate the performances on your computer.

    If you want to pay for a good AV, I would recommend you Norton Internet Security. If you want something free, I would recommend you Microsoft Security Essentials.

    After several years of using Bitdefender, I switched back to Norton. Bitdefender worked well, but started to become a memory hog. Norton FINALLY started to reduce the amount of memory it was using. No complaints about it either.

    Microsoft Security Essentials is probably the best that I have used.

    avast! Free Antivirus for Sure.

    If you are a restless internet user, the world's #1 internet security suite is AhnLab Internet Security.

    If you are just a normal user, then avast! Free is the best choice. It is world's #2 best antivirus and world's #1 free antivirus.

    I have used Microsoft Security Essentials for several years now and have never had any problems. I also tried Avast and AVG but I think it comes down to personal preference and of course being careful as to what you click on....

    for know kaspersky 2013 is the best that is available in the market. you get it provides full care to pc

  34. Tarek Ramadan
    October 30, 2012 at 11:02 pm

    For the free I recommend AVAST or Microsoft Essential i used both for long time and both are good

    for avast I suggest to enable "gaming silent mode" and close all sounds

  35. Brian Mok
    October 30, 2012 at 10:30 pm

    On my Windows computer, I have Microsoft Security Essentials installed. It does pretty well keeping all the junk and stuff out of my computer.

    October 30, 2012 at 5:22 pm

    Tough question though..presently switched to avast from MSE happy with my choice..

  37. josemon maliakal
    October 30, 2012 at 3:20 pm

    It depends , if you are regular internet user kaspersky is preferable and otherwise bitdiffender, avira, avast etc can be used ..no probs

  38. Muo TechGuy
    October 30, 2012 at 11:26 am

    The best anti-virus is this little built-in software called "common sense". Not once have I run AV , and not once have I caught any malware; you don't trust something, run it in a VM first to test.

  39. Tebawiha Lelhchhun
    October 30, 2012 at 11:17 am

    I also think that BITDEFENDER is good but i cannot say it is the best.Best anti-virus is depend on the user.Suppose you want to keep your computer safe with less memory usage.I recommend MSE(Microsoft Security Essential)

  40. Prasanth Mathialagan
    October 30, 2012 at 4:37 am

    If you are looking for free antivirus application, go for Avast. We can register for one year free license. After it expires we can renew it. If you have some bucks, Kaspersky would be a great choice. There are also some other antivirus programs out there. You can also try everything and pick the best out of it.

  41. Harish Jonnalagadda

    I'm currently using BitDefender Total Security and am very satisfied with the offering.

  42. Manuel Guillermo López Buenfil
    October 29, 2012 at 7:15 pm

    If you want a free antivirus, get Avast! Free Antivirus.
    If you want a commercial (not free) antivirus, get Kaspersky.
    They both are the best of their kind, based on several reviews I have read and my personal experience.

  43. Saurav Azad
    October 29, 2012 at 5:49 pm

    go for Microsoft security essential it is best with minimal problems

  44. Vishal Mishra
    October 29, 2012 at 5:22 pm

    you should install Avast antivirus and Anti-malwarebytes. You can install both of them together without any conflicts.You should keep your antivirus up to-date.

  45. Reý Aetar
    October 29, 2012 at 5:21 pm

    kaspersky if you prefer to pay
    ms security essential if you want free

    you wont need any if you are regular user stay updated and dont open unknown sites
    or misc unknown software.windows is a lot more secure now a days

  46. Dave Rimmer
    October 29, 2012 at 4:47 pm

    I would recommend Avas Free, Spyware Blaster, CCleaner, Zonealare Firewall, if you google it you get many more.

    There is no "perfect" security program. All of them have faults of one way or another. Some of them is not very customable. Others put a large drag on your system resources. For me, I use a combo of free software. I use MS security essentials for AV, Windows firewall for anti intrusion. I use firefox for browser as it let me add all sort of addon's to secure my computer. I use noscript for prevention of drive by infection. Siteadvisor for checking the integrity of a website. and Certificate patrol for make sure a site is what it suppose to be. And finally, I use ad-block plus to get rid of ad's.. I store my my shopping sites credentials and semi-important passwords with lastpass and evernote for taking notes. I know this is a hodgepodge of programs but it gives me infinite control I now have to understand what security is about.

    the best antivirus depends on how you use your pc and which sites you go in, for better protection total security is important and also have antilogger like zemana or other to have another security layer

    now if you installed and tested many security programs be sure that un-installation is complete (no left over of files and registry keys) since your chosen security tool if detects left over or if left over interfer with your security tool then will make windows slower.

    You had tried many antiviruses and softwares and you had messed with your system.If you like to test softwares,then you must use sandbox software like Sandboxie.

    If you are unable to clean up the mess created by the aforementioned softwares,then install them and uninstall with a good uninstaller utility like Revo uninstaller and then clean up the registry using CCleaner.

    If you want a peaceful experience while working with your laptop,then use Avast and set it to update it in background with no popup update notifications.This will make sure that you would never have to look for your antivirus program except during activation once in a year.

    To speed up file access and program load times,run Defraggler software,which is a defragmenting software used to arrange system files for faster access.

    well I use bitdefender myself but the Internet security not the TOTAL

    if you are so frustrated by the antivirus programs then may be try running PC w/out them or may be MSE, that's enough if you don't download much or you know what are you doing, like genuine installing softwares or games

  52. Lisa Santika Onggrid
    October 29, 2012 at 10:50 am

    I've used Avast for a year and couldn't be happier. No infection, sandbox feature, and all you can possibly want from a security suite. I used ESET. It was good, but quite resource intensive and a huge pain to uninstall.

    To finish the uninstallation try Revo uninstaller or Geek uninstaller. If they won't go off the normal way you can try the forced uninstallation mode.

  53. Osama Javaid
    October 29, 2012 at 10:48 am

    Install avast antivirus free, malwarebytes and advanced system care free...., use firefox, and get peace of mind.

    You can try Kaspersky Internet Security 2013. It has 30-day free trial as well and it may slow down your PC a bit, but it works great and I've been using it on my computer and it seems to be faster than the previous versions!

    Hoping this helps! :)

    Debatable and will have to try yourself, but my vote goes to Eset Smart Security 6.
    And i have tried Kaspersky, Bitdefender, McAfee, AVG & Norton, but ESET was the best for me among all!

  56. Jeremiah Iliffe

    Now there is a new version, Advanced System Care 6
    or antivirus programs
    Avira Antivirus ..?
    but AVG & Avast are also good enough
    I think for me , its Microsoft Security Essentials
    there's no perfect antivirus software , but good antivirus softwares which I have listed above
    So choose which ever u like ...
    the antivirus software is depending on u , because how much virus are u hving in ur computer , u could only know about that

      Avast! Free infact is the world's #2 according to the av-comparatives.

      AhnLab Internet Security could be the best , it is world's #1 internet security suite, recommended if you are a restless internet user.

      It's not my word, in fact it is tested and proven.

  62. DalSan Mack
    October 28, 2012 at 10:15 pm

    It is all subjective. Avast is better than AVG since AVG became resource hungry. Avira is very good, but has nag screens to purchase the full version and gives off false positives. Many here would vote for Avast and Comodo firewall for excellent protection. MS Security Essentials is mediocre at protection, and I would like better control of the firewall, so I can't fully support MSSE except for basic users. Bitdefender is a very good package to use and offers better protection than most of freeware antiviruses. Norton is very good, has been getting better every year. Kaspersky is great, but can be resource hungry. The user interface and esse of use is more of what it comes down to, and researching that would offer better ideas on that point. The biggest point I would like to make is that the testing done and the results you see are different from real world protection. Tests are good, but not all that should be looked at. I usually go for freeware as it offers almost as good protection as paid software without having to be bothered with making payments, especially when I don't have much funds.

      Another thing about tests: In 2010 or 2011, I was going through AV test results and noticed that in several test suites the free version of Avira was scoring better than the paid version.A note about Norton as well. If you opt for that, you may want to disable their toolbar since it puts a HUGE drag on your internet surfing speeds through the web browser.

    • Boni Oloff
