a friend of mine called with a pc problem. he was given a computer, i believe a pentium 4, i haven't been over yet so i'm not sure exactly whats going on.evidently it was working fine but has been sitting for a while. he knows practically nothing about computers. the problem is all the junk that is on it. it has win xp, but he doesn't have any discs to reformat. i told him it would be best to wipe the harddrive clean and start over but how does he do that or clean up the existing mess. it appears hes got some spyware, bugs and junk because he says stuff keeps popping up, duplicating itself etc. he just had dsl installed through bell south and now he's kind of stuck so he called me. he lives 30 mjinutes away so i'd like to have some decent info before i drive over there. thanks.
