System shutdown, against my will

[RSL]

Okay, I hit CTL ALT DEL and clicked the processes tab, and I see no MSBLAST.EXE... I'm really confused now...

EDIT: here's a screenshot of me getting the shutdown error along with showing my processes. No mention of msblast, unless it's something else in that list? (I'm not too good with computers unless it's the really basic stuff...)
