Hi.  I've recently been experiencing a system shutdown that displays the following message:  System shutdown in progress by NT Authority\System.  An error has occurred in C:\WINDOWS\SYSTEM32\lsass.exe (status code 128).  I've been working on this for the past few days and was able to delete all of the malware on my computer w/the help of the virus guys (using hijackthis).  Any ideas of where I can go from here?  I did run a Norton scan yesterday and today - no viruses found.  I've had this problem once before that was an RPC error, which I was able to fix.  I don't think I had a problem w/the lsass.exe file originally though.  Anyway, here's hoping :)
