I assume it's LSASS.EXE. This might be a symptom of the W32/Sasser.worm that spreads by exploiting the MS04-011 vulnerability:
http://vil.nai.com/vil/content/v_125007.htm

It is w32.sasser.b.worm

http://securityresponse.symantec.com/avcenter/venc/data/w32.sasser.b.worm.html

W32.Sasser.B.Worm differs from W32.Sasser.Worm as follows:

Uses a different mutex: Jobaka3.
Uses a different file name: avserve2.exe.
Has a different MD5.
Creates a different value in the registry: "avserve2.exe."

How to clean your machine ?


1.Download the patch from http://www.microsoft.com/technet/security/bulletin/MS04-011.mspx

2.Download Reomval Tool from here http://securityresponse.symantec.com/avcenter/venc/data/w32.sasser.removal.tool.html

3.disconnect from network

I would recommend to open your own thread for this question.

All of the above is fine, but what if you can not get the PC to boot to DOS or CD drive?   All I want to do is a format with the restore disk to clean out everyhing?   I have been on line with HP support and Microsoft and no one can assist me?

lsass.exe error just want to start clean with the recover cd, but no matter what I do it will not start it from DOS or the cd drive
even hp's support group could not help i tried everything they told me to do.
