Re: Bad Antivirus

I would also ssdeep the two files and see how different they are. will help you determine if you need to do more analysis.

I would run in a sandbox to see what the malware does and fix accordingly. or do some research as sality has been out for a while. I know off the top of my head it adds itself to the registry and adds itself as a trusted program to the local FW.

if you have the exe's that would be your best bet.

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.
