...and get a firewall (e.g. ZoneAlarm)...

yeah we used to do that all the time in class
shutdown "IP/hostname" at the command line
im not sure how to sut it off but if you type
"shutdown /a" at command line/run menu it will abort the shutdown

Actually, this is probably the Sasser worm. It just came out late Friday night. This worm exploits Windows 2K and XP machines that don't have the MS04-011 patch. It triggers a problem in LSASS.EXE, which causes the 60 second shutdown you are seeing.
Go here to read up on this:

(link also at: http://tinyurl.com/39hae)
And get the patch to stop this.
Then run an updates antivirus scan.

This is related to a couple of viruses but the most recent is as mentioned, "W32/Sasser.worm.a". This attacks systems that have not been patched with a Microsoft security update for an Exploit in LASASS. Get the patch from the following link.

To manually remove this virus follow these steps:

1. Reboot the system into Safe Mode (hit the F8 key as soon as the Starting Windows text is displayed, choose Safe Mode.

2. Delete the file AVSERVE.EXE from your WINDOWS directory (typically c:\windows or c:\winnt)

3. Run "Regedit" to Delete the "avserve" value from:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run

4. Reboot the system into Default Mode

To automatically remove the files download and run Stinger.exe from Network Associates:
