Systems Affected:

Backdoor.Volac is a backdoor Trojan horse server that allows unauthorized remote access to an infected system.

This Trojan may be found as the file, %Windir%\Avsynmgr32S.exe.

Note: %Windir% is a variable. The Trojan locates the Windows installation folder (by default, this is C:\Windows or C:\Winnt) and copies itself to that location.
