Maybe try "TrojanHunter". It's from Sweden (Michel?) and you can get a 30-day evaluation
copy. Using it and my virus software (with lots of repeated cleansings) I managed
to kill off an exceedingly nasty trojan a couple of weeks ago.

I also recommend "Spybot S&D". I don't know if spyware could be part of your problem...
but my first run of Spybot revealed a LOAD of spyware on my machine. And seemed
to really clean it out.

Also, for information, you might check the "lessons" area of www.jefflevy.com.
While you might have to do some searching through the lesson topics, you
might find something dealing with involuntary shut-downs.

Thanks so much. There are so many programs out there that I was honestly lost on which ones to try.

Ran TrojanHunter... pulled no less than 7 trojans off a computer I *assumed* relatively clean. Thanks for the post, even if it is trial... it got the job done it appears.
