My laptop is filled with Viruses and programs that I don't want and can't uninstall. I've backed up all the files that I need, and want to know if it is possible to reinstall Windows XP, so that the computer is complete wiped and only Windows in installed. When I put in the XP disk again, I'm given the option to install, and after an hour of going through the process, all the programs where still there. Does anyone know how I can do this?
