My computer is giving me a message that the NT Authority is authorizing a shutdown. The message reads that the RPC has not received a signal and will allow me 60s to save my work. It then proceeds to shut down the computer and reboot. This only happens when I am online

There are thousands of nasty computer viruses/worms looking for unprotected
computers. Your computer can be infected within a few milliseconds the moment
an internet connection is established if your computer is not properly secured.

Apparently, your computer is now infected with the W32.Blaster.Worm or one of its variants.
This happened because you have not been using an internet connection firewall and have
apparently neglected to install the critical updates available at the Windows Update website.

------------------------------------------------------------------

If your computer is constantly attempting to shutdown
or reboot, quickly go to:

Start > Run and type: CMD , and hit enter.
This opens the Command Prompt window.

Then type: shutdown -a , and hit enter.

This should halt the rebooting problem.

------------------------------------------------------------------

Then immediately turn-on Windows XP's built-in Firewall:

A tool is available to remove Blaster worm and Nachi worm infections from computers
that are running Windows 2000 or Windows XP

A security issue has been identified that could allow an attacker to
remotely compromise a computer running Microsoft Windows and
gain complete control over it. You can help protect your computer
by installing this update from Microsoft.

You have the MSBlaster worm. To remove it, do the following:

The following instructions are in three parts

1. Stop it from running

2. Remove it from your system

3. Make sure it doesn't come back



Before beginning, if you have an always-on internet connection,
it's a good idea to disconnect it.



1. Stop it from running

Press Ctrl-Alt-Delete to bring up the Task Manager, then on the
Processes tab, click msblast.exe and then "End process." Reply
"Yes" to the warning message that comes up.

This stops the worm from running, so your system will not shut
down. However, it doesn't remove it, and if that's all you do, it
will start up again the next time you boot.


***

2. Remove it from your system

a. Start the registry editor program, regedit, by going to Start
| Run, and typing REGEDIT
Navigate to HKEY_Local_Machine\Software\Microsoft\Windows\Current
Version\Run by clicking the plus signs next to each of the
folders in the left hand pane. When you get to the last of them,
Run, click the word Run itself.

Find an entry called "Windows Auto Update" on the right side.
Right-click it and delete it.

b. Do a Windows search for msblast, and delete all files found.

The worm is now gone, and won't start again the next time you
boot. But if that's all you do, you can get reinfected just as
you did the first time.

***


3. Make sure it doesn't come back

a. Make sure you're running a firewall that prevents worms like
this from getting in. You can enable the built-in Windows XP
firewall, or download and install another one such as the free
version of ZoneAlarm. To enable the built-in firewall, go to
Control Panel, double-click Networking and Internet Connections,
then click Network Connections. Right-click your connection, then
click Properties, and on the Advanced tab, click the option
"Protect my computer and network..."


b. If you've disconnected your internet connection, reconnect it.
Download and install the Microsoft patch at
http://www.microsoft.com/downloads/...8b-fe98-493f-ad76-bf673a38b4cf&displaylang=en

That will remove the vulnerability that the worm exploits.


c. Be sure you are running an anti-virus program, and that you
regularly download the latest updated virus definitions.
