Removing Win32/Sality - Win32/Tanatos

[kjcdude]

I'm looking for some support on a very large infection with Win32/Sality and Win32/Tanatos across our entire network of about 160 pcs.

I've used the following removal tools which have all failed.

For those not familiar with sality it's good to know that it kills a lot of common anti-virus processes.
I've been unsuccessful with installing avast or even getting a console only version to run.  Ideally I'd like to get avast installed on all 160 machines and have it run on next launch before windows loads.
I have been able to get clamwin installed and have ran that with the following paramaters.  'clamscan1.exe --database="C:\Program Files\ClamWin\bin" --recursive Z:\ -k -u -i --move="C:\virus" --memory'

I have found around 200-400 infected files on some computers.  Again no matter what I run it will still not fully remove the infected files and still exists on the next restart.

If anyone has any suggestions or has a company/consultant that I could talk to in regards to this large problem that would be fantastic.

Thanks,
Kyle

Cleansing Win32:Sality requires a total format and a clean reinstall on all PCs because not only it infects files but it can drop a keylogger as well.

Win32/Tanatos, another name for Win32:BugBear, is a worm that drops a trojan with keylogging and backdoor capabilities.

You could use Dr. Web CureIt.

Once you rid yourself of Sality and Tanatos, you will need a firewall (including a network firewall).

That video was done on May 26, 2009 and the infection has mutated several time since then so I would go with what miekiemoes recommends.
