NT AUTHORITY SYSTEM

[Mumtaz Piracha]

I am frequently getting the notice that the system is
being shut down. Shutdown is initiated by NT Authority
System. I have already installed Internet Firewall. Still
the notice keeps coming. What should I do? Please respond
Urgently. Thank you.

Greetings --

Enabling a firewall _after_ you've been infected won't do anything
to solve the current problem; it can only prevent future infections.

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.

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:
http://www.microsoft.com/security/protect/
(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..." Note: the built in
firewall only monitors incoming traffic not outgoing (ie
spyware, trojans, etc.. you may have on your system).)
