Perhaps you could try the sasser removal tool that Microsoft provides. It says it works for A and B, but it'd be worth trying on C too... direct download: http://www.microsoft.com/downloads/details.aspx?FamilyID=76c6de7e-1b6b-4 fc3-90d4-9fa42d14cc17&DisplayLang=en -or- Web install: http://www.microsoft.com/security/incident/sasser.asp Computer Associates has a quick web page up detailing Sasser.D. http://www3.ca.com/threatinfo/virusinfo/virus.aspx?id=39037 I haven't noticed problems on my systems yet, but that's probably because the worm travels over port 445 which I am blocking at the subnet border with IPSec.

We are also seeing this, and the Symantec tool is not detecting on our PCs either. The error message we see says, in part, "LSASS.exe termintaed with code 128."

We have a couple PCs that exhibit the random reboots that make me suspect they have been infected with the Sasser worm, but the removal tools I downloaded from Symantec have been run repeatedly on these PCs in safe mode and have not found any evidence of Sasser. According to Symantec, the removal tools cover the initial Sasser worm and variants B and C. I just wondered if anyone else has found evidence of Sasser but have been unable to get a removal tool to detect it's presence? I surmise it is some new variant that the removal tool is not able to locate and remove. Any others with this experience today? Thanks!
