Norton Anti Virus (expired), Spy Bot S&D, Advanced System Care 3, Webroot Firewall & CC Cleaner. After looking at his list, I'm not so sure these would all fall into the same category.
To get a new antivirus (which he needs) he would have to at least get rid of the Norton that has expired, but with all those quaranteened files, he's afraid it will crash. He purchased the computer second hand & there are no cd's to repair a crash. That is why I was asking what happens to the quaranteened files.
