That's not a virus, that's a head sector crash -- especially if it makes periodic clicking noises when trying to access the hard drive.
DO NOT TURN IT ON OR LEAVE IT ON as every second it stays on in that state it destroys more data
.
Unfortunatly data recovery from that kind of crash never seems to get cheaper than $500. When it happened to my PC I just decided screw it, I'll start over, and send the HDD in for replacement
