                         $F300
                      system infection: RAM resident, reset resident
Infection Trigger...: ---
Storage media affected: tests floppy disks (3.5" and 5.25") for BYTE
                         BANDIT, SCA and SCA clones
Interrupts hooked...: vertical blank interrupt (IV 5)
Damage..............: permanent damage: ---
                      transient damage: screen buffer manipulation:
                         message when detecting a known virus
                         (see above)
Damage Trigger......: permanent damage: CoolCapture is set to system
                         default, KickTag pointer is modified with
                         A.S.S. entry, DoIO vector is set to system

                         pointer are shut down
                      detects BYTE BANDIT, SCA (and SCA clones)
