                         against BYTE BANDIT', 'Something wonderful has
                         fiddled with the CoolCapture() pointer
                         (Probably the SCA-Virus) and has been
                         eleminated *** Thanks to the ASS VIRUS

Type of infection...: self-identification method: kicktag pointer
                         normally set to $0007F300 and the virus
                         compares the second word of this adress with
                         $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
                         default (Kickstart 1.2 Release 33.180)
                      transient damage: message when detecting a known

Particularities.....: other resident programs using the system resident
                         list (KickTagPointer) or the CoolCapture
                         pointer are shut down
                      detects BYTE BANDIT, SCA (and SCA clones)
Similarities........: produces a sequence of notes similar to the
                         SYSTEM Z (antivirus) virus series
