Device Driver Error (aka: blue screen of death)

I am getting the blue screen of death quite often telling me of a device driver conflict (irql = not less then .. whatever).. similar to the problem that other people are having. I have yet to see what the driver is that it's having issues with. I believe that a virus got me. There are two hidden files on my computer that I can't locate. They may be the culprit, but I've done a search on these files and nothing. LFRARMAP.EXE & MSRYDOC.EXE. Does this sound familiar to anyone? Norton, AVG and Adaware can't do anything about them. If anyone can point me in any direction to try to solve the problem, that would be most helpful. Thanks!
