The Sasser Worm Virus is a nasty piece of work. It was developed by a Russian hacker who was later arrested for starting the virus. You'll know that you have been infected with the Sasser virus if you start your computer and it automatically shuts down after a minute or so.

You might get the following errors: "lsass.exe - system error An invalid parameter was passed to a service or function."

When you click OK, the computer will simply reboot.

Some people get: "lsass.exe - system error"

When they try to update a password, an error message state that the "value provided as the current password is not correct."

Again, your computer restarts.

You will certainly know that you are infected by the Sasser Worm virus if your PC counts down to zero and shuts down completely. The warning error message will say: "This shutdown was initiated by NT AUTHORITY\SYSTEM". And that the "System process lsass.exe terminated unexpectedly".
