Comp keeps shutting down on me. Help!

[Guest]

My pc display:

This system is shutting down. Please save all work in progress and log off.
Any unsaved changes will be lost. This shutdown was initiated by NT
Authority/system. Time before shutdown: Message the system process
'c:/winnt/system32/lsass.exe' Terminated enexpectedly with status code
1073741819. The system will now shut down and restart.

It won't stay on for more than a few minutes. I ran ad-aware and it didn't
help. I don't know what else to do, please help.

Sonds like the MS Blaster. Do You Have windows XP? if so You probbly see the
meassage when u get on the internet. So the next timeyou see that meassage
try to:]
click on Start
and then Run
In the Run Prmpt type shutdown -a
(this should abort the shut down) now since u do not have to worry about the
computer shutting down u should go to windows updates and see about getting
the critical update related to the ms blaster worm (last time i check it was
called "Windows XP MS-Blaster removal tool").

Megan,

Apparently, 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 from Microsoft.

If your computer is constantly attempting to shutdown or reboot:
Start - Run, type "shutdown -a", and hit Enter.
That should halt the reboot. Now fix the problem.

Immediately turn-on Windows XP's built-in Firewall:
