My son's computer I think is infected BIG TIME. He's uninstalled programs he doesn't use & got free space, the trouble is this: No free space showing; Can't defrag, say's no free space; Can't restore because it say's it's suspended itself as no free space. Windows now pops up and says' Windows your using is a countifit one, it's not. Cant install any antivirus programs, due to no free space. When he deletes his music it deletes everything else and puts on all this porn. How Do I FIX this without having to pay someone again to mess it up? Last time if was fixed they loaded Windows Professional on it and here all the problems start. Please help

Note: Last time it was fixed they loaded windows pro on it If that is not the os you purchased with the computer then it would probably be recognized as counterfeit and "they" owe you you os back.
