I can't seem to post a new topic in the 4.5 forum for some reason...the "new topic" button just isn't there. But maybe this is a common problem in other versions, I don't know....I have Avast 4.5 with Windows XP Pro , Pentium III PC...basically about every other time that I start up my computer, the little Avast icon in the tray starts spinning and when I double-click it, it brings up the resident protection box, and shows that it is scanning files. I don't want it to do this for no reason, it slows down my computer significantly. If I Terminate it, then my virus software is off and I don't want it to be off completely like that. Does anyone have any suggestions? Thanks.
