you can prevent it from doing the autoshutdown by changing the RPC service properties in windows management. i just set mine to attempt to restart the service when it failed instead of making me reboot.
i'm at work right now, when i get home i'll get the damn thing outta my system.
what annoys the crap outta me is that it came in via an open port, not even by my own stupid email or whatever. i havent downloaded a virus that i can remember but this somsqueak found me.
