omg that is so incredibly annoying!
mine started last week, and then for a week it didn't do a thing. i called Dell and they told me that i'd have to delete everything dled from the comp (including kazaa

) and then go to Run and delete the virus wherever it popped up.
of course i thought it was fixed but NO! yesterday like everytime i opened up anything w/ Microsoft, (i thought....but i guess it was thru the internet other than AOL) it kept shutting off!
this really sucks. i thought my comp was alone

sorry you all are dealing with this too!
