rikvm_1628BCEA.sys

For the fourth time, Power Eraser has found and allegedly removed the above item.  I have NIS 2012 with latest updates and the PE i used was freshly downloaded so it it the latest version this date .I use Windows 7 64bit.  Yes, I did a search of this forum and found a couple of old references to the above item. No "funmoods" or whatever thing is on my computer and don'r recall ever seeing anything so described. I even have tried that Malwarebytes free program someone suggested but that never finds anything after I run my NIS.  Please advise what rikvm_1628BCEA.sys and how I can permanently resolve this "bad" item.  Thanks
