I have a Compaq desktop s5200cl. it is a real sick unit. I know it has many spyware programs and alot of infection from viruses. I just don't know where to start to clean it up. I can always just reformat, but I would rathe not do that cause I'll lose some very important files, however, infection is so bad I am unable to even dump those files to CD to preserve them. Can any one give me help?
