that cant be a virus attack, it was a blaster worm which initiated a shutdown call from RPC. but that was patched nicely in SP2.
So i donn think its a virus, but you should always give it a check, cause no driver installation will try to shutdown this way..
and if u want to stop this shutdown message u can do the following in those 60 secs of death
goto Start>run>cmd
type shutdown -a
and it will abort ur system shutdown for that time..
good luck and after performing a virus check and cleaning ur drivers completely with some driver clean utility try installin drivers once again and preferbly download the latest ver. of drivers
