System Shutdown won't stop

[Aaron]

I just recently bought a Toshiba laptop. Now for some
reason the System Shutdown message box pops up after I
start up my laptop. It gives me one minute before the
shutdown will occur. After time runs out it restarts my
laptop and the same thing happens all over again. I've
restarted and shutdown my laptop but after I turn it back
on the System Shutdown process starts up again. Can
somebody please help me. This is what the System Shutdown
screen says:

System Shutdown

This system is shutting down. Please save all work in
progress and log off. Any unsaved changes will be lost.
This shutdown was initiated by NT AUTHORITY\SYSTEM

Time before shutdown: xx:x1:00

Message
Windows must now restart because the Remote Procedure Call
(RPC) service terminated unexpectedly

I just recently bought a Toshiba laptop. Now for some
reason the System Shutdown message box pops up after I
start up my laptop. It gives me one minute before the
shutdown will occur. After time runs out it restarts my

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://download.microsoft.com/downl...e-b7a52a983f01/WindowsXP-KB823980-x86-ENU.exe

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.

You have the RPC vulnerability and have been attacked.

Get current virus software.
Run windowsupdate.microsoft.com to get patched.
There's a a procedure on the anti-virus sites to manual
remove the RPC attack.
