Big Gluck currently affects Windows 95/98 PC's.

The "server" portion is named "bg10.exe". It's approximately 100Kb in size and can usually be found in the either the WINDOWS or WINDOWS\SYSTEM directory.

Port 34324 (by default) is used to establish the connection between the "client" and "server".

Once installed, it is rerun every time the computer is started by means of an entry under the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices" branch in the Registry.

How to Remove Big Gluck

The first five steps involve editing the registry and although the steps are relatively easy, I cannot be held responsible if a mistake is made. Please use caution.

Step 1.
Click START | RUN
type REGEDIT and hit ENTER

Step 2.
In the left window, click the "+" (plus sign) to the left of the following:
HKEY_LOCAL_MACHINE
Software
Microsoft
Windows
CurrentVersion
RunServices

Step 3.
In the right window, look for a registry key with a Data value that loads the "bg10.exe" file. This is the registry key that provides the ability to load the server portion of the trojan whenever the PC is started.

Step 4.
In the right window, highlight the registry key that loads the file and press the DELETE key. Answer YES to delete the entry.

Step 5.
Exit the Registry

Step 6.
Click START | SHUTDOWN. Choose "Restart in MS-DOS mode" and click OK.

Step 7.
After the computer has restarted, change to the WINDOWS or WINDOWS\SYSTEM directory (e.g. CD WINDOWS or CD WINDOWS\SYSTEM) and delete the "bg10.exe" file (e.g. DEL bg10.exe).

Step 8.
Press CTRL-ALT-DEL and allow Windows to restart.

Congratulations, Big Gluck has now been removed from your system.
