Summary

This is not a virus, but we sometimes get support calls about it.

Bang is a Windows-based game, which is distributed in BANG20.ZIP. It will display an icon with the text 'Death To Mickeysoft', and will change your mouse cursor to a crosshair and allow you to shoot holes to the visible windows.

In addition to that, Bang inserts the following lines to your WIN.INI:

 
  [BANG]

 
     BBBBBB         AA       N     N     GGGGGG
     B      B     A    A     NN    N    G
     B      B    A      A    N N   N    G
     BBBBBB      A      A    N  N  N    G   GGG
     B      B    AAAAAAAA    N   N N    G      G
     B      B    A      A    N    NN    G      G
     BBBBBB      A      A    N     N     GGGGGG

  Each WinDoom application is adding some rubbish to the WIN.INI
  file. This one too !!!

 
  Enjoy it

The game is harmless and can be considered to be a joke.

Note: This joke has nothing to do with WINDOOM.EXE, which has been used to distribute the DMSetup trojan. See DMSetup for more information.
