If your having problems with this driver, try using a USB keybaord and mouse and disable the PS2 driver
   
Has been known to become duplicated and infected with a browser hijacking rootkit. TDSS Killer solved this in my instance.

This is the file (or one of the files) that the malware group "alureon" took over to redirect my search results. It's otherwise needed for PS2 control (keyboard/mouse)
