Apparently, your PC has suffered a major security breech and is now
infected with Malware (i.e. "a viral worm") because:

1. The latest Windows XP Critical Updates have apparently not been installed......
2. The PC's firewall apparently has not been properly enabled.....
3. Out-of-date or no AntiVirus program has been installed......

If you have Sasser, follow these directions to remove it from your computer:

Amazingly, a worm or virus can enter your PC the very moment
you establish an internet connection and have not enabled a firewall.
You don't have to visit any website to become infected. Chances are
your PC running Windows XP has indeed contracted the Sasser worm.

If you have Sasser, follow these directions to remove it from your computer:

| Amazingly enough I came to this newsgroup to ask this very question. Supposedly the sasser worm is connected
with lsa shell. But it may not be the problem. See artcle:
|
| http://support.microsoft.com/default.aspx?scid=kb;en-us;300038
|
| I received an old computer that was running windows 2000 on a network. I removed the hard drive and
installed XP clean on a new hard drive. Once connected to the internet the first time I received the above
error message within 5 minutes of being online. I did not go anywhere online except the MSN homepage.
Basically, unless I received this sasser virus from MSN I could not be infected. But my symptoms are exactly
the same as Nick.
|
| My question is: when windows 2000 is being run on a network, can there be any residual code left in the BIOS
or in the DOS start-up? Having removed the hard drive no part of the 2000 OS can remain on the computer, or
can it? The above article is for windows 2000, but the exact symptoms are ocurring in XP. Is the cause exactly
the same? Can the same Hotfix be used?
|
| I also read that LSA shell can cause problems when memory is low. I intend to increase my pagefile space on
my disk. Does anyone know anything about this?

Greetings --

You've apparently contracted the latest worm, W32.Sasser.Worm,
specifically designed to attack people who do not update their
computers promptly and who do not practice "safe hex." In other
words, like Blaster, this worm was developed and distributed _after_ a
patch for the vulnerability was announced and made publicly available.
Further, and also like Blaster, this worm could not affect any
computer whose user had taken the basic precaution of using a properly
configured firewall.

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.
