This virus has been posted on a number of usenet newsgroups as infected Macromedia Shockwave animation files named:
BOXING.EXE, FUN.EXE and NOSTRESS.EXE.

If you run the file, it displays a picture of a boxer that can be hit by a punch chosen from a displayed toolbar.
The virus will runs before this animation.
    It chooses a random letter and then searches through the directory tree. It compares the first character of all files with the one previously chosen.
    If the characters are the same, the virus infects the file.
If the current date is different from the date of the file infection, the virus launches the payload.

The payload randomly changes the icon arrangement on the desktop so it appears that icons are running away from the mouse pointer. It may mutate so that it is not further infectable, but still deletes a number of randomly chosen files, depending on the date.
