Lsa Shell application error

[Tony Darling]

Has anyone encountered a problem where the application
Isass.exe is "having problems and needs to shut down"?
This happens regularly about 30 to 60 minutes after
logging in. When it occurs, it counts down 60 seconds
and then does an orderly shut down and restart. Upon
restart, I am prompted to send an error report to
Microsoft which I do.

Thanks,
Tony

Your system may be infected by a bot software which exploits the
vulnerability of the LSASS.EXE.
To abort the shut down, click Start, click Run and type "shutdown -a"
(without quotations) and press OK.

Then download and install the critical update IMMEDIATELY from
