Windows NT Crash

[Alastair MacFarlane]

Dear All

I have posted this question on 2 sites WindowsXP.general and
IE55.General.discussion) because I unaware which site group will hold the
answer to my problem.

After about 5-15 mins after logging onto the internet using IE5.5, I get an
error which causes my whole system to shut down. It states that the NT
Authority is shutting me down within 60 secs because the RPC service has
crashed. Can anyone suggest how to fix this problem or indeed the nature of
the problem in the first place?

It is a standard Professional build of XP (disk probably six months old)
with no updates or service packs. There is little software Outlook, Office
and some DVD writing software. NO virus software or personal firewall
software.

Please help me with my problem.

Alastair

Hi,

It appears your computer has been infected with the Blaster virus. For more
information and how to fix this please see follow this link:

Your last sentence holds the key to your problem. 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.

Greetings --

First, you cannot possibly have IE5.5 on a WinXP machine. WinXP
ships with IE6, and it cannot be downgraded.

If you connected the PC to the Internet without having first
installed the KB824146 Hotfix, without having first installed an
antivirus application with current virus definition files, and before
enabling a firewall, 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.
