I've just inherited my parents old computer system which was replaced by this new Dell I'm on now. I plan on hooking it up in my bedroom so I dont have to use my housemate's anymore when at home. It's a pretty good computer from what I understand (i dont understand much when it comes to PC's), however I think it is infected with spyware plus it has loads of programs which are of no use to me and probably slowing it down. Do I need to get my friends guru out to clean it up or is this something that I can do ??
