spooldr.sys? ran combofix

My computer has been getting BSOD, and Microsoft said I had spooldr.sys. I can't find it anywhere on the computer, though. I went through the steps recommended with Read and Run Me First Malware Removal Guide. Nothing was found until I used ComboFix. Combo Fix deleted fad.sys and winhelp.ini. Under rootkit scan it says:

I am guessing this is the spooldr.sys program. But maybe I am wrong about that. Anyway, any advice about what to do next? I can post the whole combofix log is that is helpful.
