This usually happens when a drive is moved from one system to another because the file is the process Generic PCI IDE Bus Driver. This is a XP or Vista install and you cannot even get into the bios on the system and what Znod suggested is a good way to go or run sfc/ scannow if you can get into safe mode. Google search gives quite a few version of this problem and in fact sites are selling the file. I never let updates install automatically always check them out to see what they are about, but that at this point is nether her nor there.
