Theres a nasty worm going around infecting all users called W32 blasterworm as from yesterday (August 11th).
It shuts your computer down and also affects system restore and access to windows updates.
Microsoft call it "critical".
Go to http://securityresponse.symantec.com/avcentre/venc/data/w32.blaster.worm.html
and look for a tool provided by symantec to remove the bugger!
It will then ask you to download and install a patch from microsoft.
I reccomend you all do this A>S>A>P !!!!!!!!!!
