More Information

This backdoor Trojan installs itself in the Windows system folder with the filename tskmngr.exe, and changes the registry in such a way that the Trojan is run every time Windows is restarted.

The Trojan contains a simplified IRC client which, on every subsequent restart of Windows, uses the computer's internet connection to announce itself on a specific IRC channel on irc.dal.net. This allows other people with the client software to access infected users' computers.
