Hello everyone. Newbie forum member here.

I'm mainly here to learn from all the great advice given out by the veterens, but I believe I may be of some assisstance here.
I had this exact same problem on my Wxp Home computer late last year.
If you turn on Internet Explorers imbedded firewall it should prevent your computer from restarting. This should give you time to rid your PC of the virus and patch XP accordingly. In fact, I'm surprised you were able to get online and download the patch/fix tool without getting booted (that is if your firewall is turned off).
If your firewall is already turned on, then I'm not sure.
Make sure you take note of the system restore section of the fix as well.
