Threat description


Type: Virus
Platform: W32
Aliases: MrKlunky


This virus spreads under Windows 95 systems. When an infected EXE is executed, it drops a VxD file. This VxD will be loaded when Windows boots and will infect any EXE files which are opened.


Automatic action

Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.


More information on scanning and removal options available in your F-Secure product can be found in the Help Center.

You may also refer to the Knowledge Base on the F-Secure Community site for more information.

Contact Support

For further assistance, F-Secure customers can request support online via the Request support or the Chat forms on our Home - Global site.

Technical Details

Sometimes the virus will fail and just damage EXE files instead of infecting them. Names of all infected files will be written to C:\LOG.LOG.

The virus contains these texts strings which are never shown:

SYSTEM\CurrentControlSet\Services\VxD\MrKlunky         MRKLUNKY_DDB 		 		

Otherwise the virus just spreads.
