    In my opinion, Windows 10 Antivirus is the best and lightest

    Hey what AV would you recommend today? What do you think about 360 total security?

    thanks for sharing this information with us, most of the people use free antivirus and they didn't know sometimes they are doing some wrong thing.

    What is the feeling about Panda Av? I have run the free version without apparent problems

      @Bruce: Panda AV is good but heavy.

    one more thing avast indeed used too much disk speed while I had HDD what I did is to upgrade to a SSD and there was no more problems with disk usage btw I am using win10 thats why I had to upgrade when I had those problems with avast I simply reinstall it.

    that is true about avast avastsvc.exe sometimes using too much CPU however I had
    ESET Smart security and once eset nod4 and I had each one for one week I had tested few av tools including eset after 2 days after installation when I log on to windows the eset appeared on screen as normall however computer have frozen and after 10 mins the blue screen of death appeared in both versions I had no choice but to reinstall windows.
    since than I don't trust eset.

    I had norton internet security but it was too expensive fo one year of full version.
    I also had avira free antivirus but when I try update it needed 3.4 GB of data to download what is even more expensive and also it was annoying by telling me that I have viruses in my coputer what is even worse it took into quarantine the windows system files (.sys) that are part of windows after what I had to restore entire system in earlier point in time and that was happening too often.
    I tried with AVG but same as avira and norton too expensive for maintance.
    microsoft security essentials – not safe enough IMO
    bit defender – not good enough and scan took long time also avast was tested by trojan hourse and only avast found it.
    kaspersky internet security – as soon as I install I had to restart and than BSOD repeatlly appeared and I had to boot in safe mode to uninstall.
    I have tested a lot of antiviruses and IMO only avast proven worthy.

    reasons why avast:
    – easy to maintance
    – free to use (only thing you need to do is register it every year to obtain new licence and it is free)
    – small update data package (approximately 10-50 MB)
    – small disk space usage
    – when detecting a virus first avast is trying to repair the file and then if not succed it removes it into quarantine in difference for other antiviruses who removes it immidiatlly no matter if it is a vital file or not.

    TAKE NO OFFENCE but I think this is more than enough reasons to keep Avast over other antiviruses.

      Avast seemed good until I got a virus while running it, and yes I kept it updated. As for all those othere issues with BSOD and every virus program you tried…. Ummm…… take no offence but the only common denominator seems to be you.

        I didn't say that avast is the best of course there is no 100% secure tool to help you against every existing threat on the net or anywhere else. There is no perfect antivirus!
        that means you can get infected by using any antivirus mentioned here including avast.

        I just mentioned my favorite antivirus and why I use it.
        I also mentioned why I don't use other tools.
        Of course you may never experience those issues but I don't want to risk my data trying all of them again to see if any of them are better than others.

        You can use your own antivirus I didn't demand you to use a specific one!
        If you don't like avast that's ok but don't criticise those who like it.

    what about avast free antivirus?


    • lakonst

      @kiki443: Avast is a pretty good antivirus too, but in some cases slows the system (or causes high disk usage).

    Haven't you heard about ESET, it should be in the top of the list

      @ashok sharma: ESET is an excellent antivirus but doesn't offer a FREE version (Only 30-days Trial).

    I had Prey installed on a laptop and a desktop when I was in college. Back at home I dont need Prey but have not found a way except going deeper in my pc than I am comfortable with.
    Without changing a bunch of stuff inside , do you know of anything that will remove prey?

    Great website! Thank you very much. One question: how do you get rid of AdChoice ads? I've tried everything that I can think of and the only way I've found is to buy Adguard but I'd like to not have to use software to block the ads.

    Thanks again.
