| Damage: | Permanent damage: 1,3-4 same as SADDAM virus: 1. If no Disk-Validator program exists on disk or no L: directory, both are built (re- placing Disk-Validator program on disk). 2. Virus destroys a block by writing "RISC" over existing data; different from SADDAM v. 3. Virus makes Bitmap NOT VALID, so running Disk-Validator next time will infect System. 4. Virus starts diskhead stepping in all floppy drives and writing on disk (if writeable) which will result in trackdisk errors. Transient damage: Mouse pointer will disappear, and an Alert will be displayed with text: "RISC VIRUS".
