Hi,

might be off-topic but:
it is the meaning of a mailing list to discuss things in here, i am realy upset when i read in a list or a forum things 
like "PM for more details" or "send you the answer via PM", i mean are we here to share knowledge or to keep it secret?!

Hello,

You can compare the actual (safe) exe with the infected ones with
something like windiff.

I would recommend removing the infected exe, if u have a backup, and put
the infected in a sandbox and run tests.

If I was in ur situation, I would track each action performed by the
infected exe by tracking network activity, processes called and so on.

Please PM me, if you need any personalized guidance.

I though I would change the world, but they wouldn't give me the source
code.
So I ended up hacking it!

Subject: Bad Antivirus

Dear folks,

I have 3 W2K3 servers, each are running same software binary exe files.
One month ago, they infected with some rootkits and viruses which later on I
know from antivirus detection this malware called sality, ipz, etc.
After installing a new antivirus and revealed the malware, some of my
software seems not running as expected. At the moment, I suspect that the
malware still there because the AV may not capable to clean them all. I tried
using 3 or 4 most popular AV, but all were claimed the servers are clean
while my software couldn't run smoothly. In fact, some of exe files has been
changed in size while I am not sure whether this changed made by viruses or
'bad' AV I just installed.
If I try to proof that my exe files has been changed by this 'bad' AV,
does anyone know how to proof this things ? By reversing this exe files, is it
possible to get which part of the files has changed ?

Thank's
