Systems Affected: Windows

Once executed, it drops the following file:
%System%\vcmgcd32.dll

Note: This file is a copy of W32.HLLP.Sality (MCID 6686) and has back door and keylogger capabilities.

The virus then appends the following lines to the file %Windir%\System.ini:
[MCIDRV_VER]
DEVICE=[RANDOM_NUMBER]

The threat injects the vcmgcd32.dll file into all running processes.

It then resides in memory and infects all portable executable files it finds.
