My parents desktop which runs on Windows XP has been infected. My dad turned his computer on and a fake anti-virus program prompted him for installation. It also changed the desktop background to a fake warning message. Avast detected two infected files one was in my documents, and the other is in a WINDOWS file. I can't delete that file repair it. When I try to repair it It sais access denied. Will I have to reinstall XP or what? plz help
