WordMacro/Demon.A consists of three macros. It does not contain any destructive activation routines, but might cause some incompatibility problems. The virus stores some of its own settings in WIN.INI.
Virus contains a routine which the author of the virus can use to easily check wheter a machine is infected or not. If the words "Dark Master calling" are written under Word and they are selected with the mouse, the virus will bring this message to the screen:
