Fuckng Computer

My computer is infected with a virus. I can not get rid of it because norton can't do anything. I can not update my OS because the one that I"m using right now is illegal and will not update. The reason I have an illegal copy is beacuse I had to format my computer earlier was due to some massive spyware that slowed my computer down 50% and adaware could also not get rid of. My legal OS's boot disks and cd are not being recognized by my computer. Until I figure out what is happening and what I can do about it I will not be online nor working. This really sucks so I hope I can figure something out soon

I can't install my os anymore, the boot disk/install disks are all corrupted and aren't being recognized anymore so I no longer can install it. So I'm basically screwed since my parents wont loan me any money for a computer that isn't shit nor a OS.
