Antivirus updates: Does it slow down computer

  1. I installed Avira (free version) and Malwarebytes Anti-Malware, for protection last year. I update very regularly. Every week there are updates available and the size of the update files is quite significant.

    My computer has become terribly slow.

    Can the accumulation of these updates (files) slow down the computer? There is no end to the updates. Does the update remove the previous versions or do they just keep on accumulating on the hard drive? If they do, how do we remove the previous versions, to free memory and make the computer run faster ( at least as fast as it used to run before ).

    I recently uninstalled Avira because everything was slowed down. I installed MSE instead and things are back to normal.

    AVIRA, like other such tools, can slow down things while updating but not after it has finished. And it’s actually light on resources.

    MSE is somewhat lighter still but doesn’t offer as good protection. I wouldn't advise you to change.

    However, you should set AVIRA to update automatically every day. Even the free version does so several times a day. Updating once a week puts you at risk against new viruses. And makes update files very big.

    I'm using avira free and malwarebytes, and I update both regularly everyday, but I never experience slowdown on my computer.. (my spec: aio pc, win7 home premium, 2GB ram)
    Just like bobcat said, my computer only a bit slowing down when updating only, other than that, no problem happens. :)

    try defrag your harddisk. Or, maybe there are too many software running on background

    I never had much luck with Avira but have heard its good. (Malwarebytes-antimalware) M-bam, you update it prior to a scan. You can update M-bam several times a day but I don't think its necessary. I myself use Avast,M-bam,SAS,Spybot S&D for scanners & of course SpywareBlaster. I got all them here
    As previusly mentioned, set Avira to update automatically,better protection. Good luck.

    Be prepared to swap around. There's been some top rated programs that I've not been happy running. There's enough high quality freeware to enable you to be selective. What's great now may well be second best next year. Just be sure you keep AV definitions updated and run regular scans. Your choice of Malwarebytes free is a good one.
