SYMPTOMS

After you install an Internet-based file sharing program, such as BearShare, you may receive the following error message:
The system process LSASS.EXE terminated unexpectedly with status code -1073741571. The system will now shut down and restart.
If you restart the computer in Safe mode, you may receive one or more error messages similar to the following:
Svchost.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log will be created.

CAUSE
