I always thought the Casino DOS virus was pretty inventive. If an infected file is run on the payload date, it moves the FAT to RAM and warns the user not to shut down their computer. The user plays a game with IIRC a 1/17 chance of winning. If they win, the FAT is restored, else it's gone. I think it's an interesting way of holding the PC hostage. A video of the virus in action: https://www.youtube.com/watch?v=wdZJHvBRRqg https://www.youtube.com/watch?v=wdZJHvBRRqg, that channel has loads of videos documenting DOS/Win9X viruses. Some are very creative.
