lsass.exe

[Rene]

My Win XP home has suddenly started to give the following
error message and then shut down whenever I connect to my
ISP for the internet or email:

NT AUTHORITY\SYSTEM
C:\system32\lsass.exe terminated unexpectedly with status
code 1073741819

When the system re-boots, there is another error message
that the LSA shell (export version) encountered a problem
szAppName lsass.exe

Any ideas how I can fix this please?

You have the Sasser worm. Read

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.
