Sasser questions

by jonah jones / June 20, 2004 4:37 AM PDT

a zone alarm alert informed me that LSA shell export version was trying to access the internet...

i said "no" and started looking for info....

according to AVG, i'm clean
Symantec says "no sasser worm found"
a search on my PC says that i have 4 copies of lsass.exe, but they are all dated 2001 (XP pro)

questions: do i have the worm or not? if yes, what now?

lsass.exe is part of the XP o/s.
if both Symantec and AVG say no worm you do not have a worm.
hope this helps.
lsass.exe listens on port 500 for UDP and if ZA tells you that your LSASS is trying to connect, you are well to deny although I am unaware of any decrease in functionality as a result of the denial.

I have the same thing happen to my computer today, and I ran a Norton scan on my computer. It said there were two problem files-I thought I deleted them. But still my computer kept rebooting itself. Finally I looked for the lsass.exe file and found 4 of them as well. I downloaded the removal tool and that said there was no worm. So how can that be? I have the same problem as you--so if there is not the sasser worm on it then whar is going on?
