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.

Deadbrain.

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
