Wow... Avast! seems to be popular here. I agree... it's pretty good. If you have that, ClamWin, and NoAdware.. then you're all set. I particularly like the fact that Avast! has a "virus chest". It's annoying when other AVs delete your programs because, even though you've used them forever, they are apparently trojans. (Yeah, I'm talking to you Norton) With Avast! though.. you can restore quarantined files.
