Getting System Shutdown due to RPC call violation

J

Jim Gallagher

Has anyone gotten a System Shutting Down in 60 seconds
message due to a RCP call violation? I have seen this
now on two different reinstalls. It only happens when I
am online (via modem) and either web surfing or
downloading software. Any suggestions?

Always run a firewall and anti-virus programs on your computer at all times.



You are infected with the Blaster worm virus.



To stop the rebooting/shutdowns, right click on the task bar, choose task
manager, processes tab, look for msblast.exe. Highlight it and click end
process. Then turn on the xp firewall.

To turn on the firewall: control panel, network and internet connections,
network connections, right click your connection, properties, advanced tab,
check the protect my computer box. Do this as quickly as you can once the
desktop comes up. Then visit the sites below for the removal and patch info.

Also make sure to follow the links to the Microsoft pages for the patch or
visit windows update for the patch after you remove it.

Yes, *thousands* and thousands (if not millions) of people have.
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://support.microsoft.com/?kbid=824146 or

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.

Greetings --

If you connected the PC to the Internet without having first
enabled a firewall, without having first installed an antivirus
application with current virus definition files, and before installing
the KB824146 Hotfix, you're very likely to get infected from any of
the thousands of PCs on the Internet that are constantly broadcasting
the Blaster and/or Welchia worms. It only takes a few seconds of
exposure.

To stay on-line long enough to get the necessary updates, patches,
and removal tools, click Start > Run, and enter "shutdown -a" when the
next RPC countdown begins. This will abort the shut down. Also, make
sure you've enabled a firewall before starting, to preclude any more
intrusions while getting the updates/patches/tools.
