I got a BSOD from Adobe Flash player (the first one I've had since Win98, and I've used NT, XP, Vista, and 7 since), to be fair, I partially caused it to crash by skipping ahead rapidly, but Adobe was DLing update when it happened. Applied that update and have had one update since (the one with the Mcafee crap). My PC is ok after a complete reboot, but that really put my undies in a serious twist.
