Avast is really good, I dont pay for it but the paid version has a program sandbox, so if I don't trust a program (or WOT says that its a bad site) Ill just run it in sandbox mode.
By the way, I hear that its a good idea to clan out your cache if you get something bad, apparently some viruses reinfect from there.
