If you know how to open your Task manager you can view currently running processes. If you find one called "msblast.exe" you have it. Kill the process. Then perform the update.

You can also kill it through the registry but unless you are very comfortable running around in there I don't recommend it. You can cause more damage than you can imagine. Still, if you're brave...

1. From the Start menu choose RUN
2. Type REGEDIT then click OK
3. Open the tree in the following sequence: HKEY_LOCAL_MACHINE
SOFTWARE
MICROSOFT
WINDOWS
CURRENT VERSION
RUN - click on this folder to open it. You will see a number of keys and values in the right hand pane.
If you see an entry under "Name" that says "windows auto update" with a value "msblast.exe" delete this key. Note - there is a folder down the tree called "Windows Auto Update" that is supposed to be there. Don't touch it. It's not the virus location.
-You will have to restart your PC for the registry change to take effect.

NOTE AGAIN - IT IS BEYOND FOOLISH TO RUN AROUND IN THE REGISTRY UNLESS YOU ARE VERY CONFIDENT OF WHAT YOU"RE DOING> PLEASE BE CAREFUL!

If you don't already have a firewall, get one and keep it up to date. Firewalls are your friend. Since I installed one on my home PC I can't believe how many times something's tried to hit me. Good luck.

thanks, I opened my task manager and didn't see it.

I've update my Anti-Virus software (Panda) and am running a scan now, just to be sure.

Kill the process. Then perform the update.

Also, remember to stand on one foot, wave a dead chicken over the keyboard and chant praises to Microsoft while performing the update.
