I am a computer retard... much help is required, thanks

[Fabi]

I was just wondering i am having problems with something,
I figured it has to do with windows. When i turn off my
computer, a sign comes up saying something like NT
Authority systems is encountering a problem and must shut
down, please save all of you work or it will be lost. It
mentions remote procedure, and before i can do anything
it just dies and shuts down if any of you have any idea i
would really appreciate some advice thanks.

Fabi;
You most likely have a worm W32.Blaster.Worm
DISCONNECT the subject computer from any network IMMEDIATELY.

Install or enable a firewall IMMEDIATELY:

VERY IMPORTANT to follow ALL steps, closing ports or installing the
patch is NOT enough.
Download the appropriate patch referenced in Ron Martells article
below.
You may need to do this at an uninfected computer and burn to CD or
save on floppy.

This is the IMPORTANT fix by Ron Martell:

After this is resolved prevent similar occurrences by installing ALL
Critical Updates from Windows Update.
Keep antivirus up to date and run at least weekly.
Install or enable a firewall.
