Yesterday my computer got some sort of virus that keeps on popping up disguised as Windows Security Center every other second or so. No matter what I do it won't get deleted. I tried going Control Panel and nothing I click on works anymore. It keeps on saying "it's not found" so I downloaded Norton Antivirus.
The results keep on showing up as internal system error "backdoor something something virus" "atapi.sys/system etc.... has been infected and needs manual removal" so not knowing what it was, I deleted Atapi.sys.......
Now my computer won't let me download anything and the sound doesn't work and Norton keeps on detecting the virus and blocking it.
Anyone know how I can restore deleted files or download atapi.sys again? I tried installing Windows SP3 but my computer keeps responding to any download attempts with the X and application cannot be found.
My computer is seriously a mess. Please help me out!!
