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.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
In addition to that, Bang inserts the following lines to your WIN.INI:
[BANG] BBBBBB AA N N GGGGGGBB A A NN N GBB AA N N N GBBBBBBAA N N N G GGGBB AAAAAAAA N N N GGBB AA N NN GGBBBBBBAA N N GGGGGG Written by REMBRANDT, POWER MIKE and JOSH 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.
