Threat Description



Aliases: MrKlunky
Category: Malware
Type: Virus
Platform: W32


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.


Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.

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

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.
