Henry,

Great, sounds like we're making progress.

The lsass.exe exploit has been used by a lot of bad guys - the most notorious
was Sasser, but there have been others. We can guess about it, or you can solve
the problem. Please don't just delete lsass.exe - it is a legitimate Windows
file, and if you delete it, you might not be able to login to the computer.

What You Should Know About the Sasser Worm and Its Variants:

The legit lsass.exe module should be in I386, and in Windows\System32. If
there's one in Windows\System, you may indeed have a bad one. Please don't
delete it (even if you can). Please read my online malware analysis article:

Use Jotti and Virustotal, and please report your findings.
