Categories:

Description:
Disguises as the Bat! email client and DVB services.
Disables the Windowssecuritycenter and enables the Windows Explorer to pass the Windows Firewall.
Runs in backbground and hooks up to winlogon to get started at any Windows boot. As long the file bmtdhh.dll in system32 directory is active, the other files of this trojan are hidden from the WindowAPI (i.e. invisible for most applications including Explorer).

If the file bmtdhh.dll remains active in winlogon, it can recreate some of the other files and settings, to disable the file it is required to reboot windows in minimal alternate shell and rename the file manually.
The filename is static and it is located in the system32 directory.

The Windowssecuritycenter may need to be reinstalled to function properly.
