Easy Identification.: typical text: "      The AMIGA Freak
                                      copys :"
Type of infection...: system infection: RAM resident, reset resident,
                                        bootblock infection
Infection Trigger...: reset (CONTROL+Left-AMIGA+Right-AMIGA)
                      operation: any disk access
Media affected......: only floppy disks (3.5" and 5.25")
Interrupts hooked...: vertical blank interrupt
Damage..............: Permanent damage: overwriting bootblock, maybe
                         destroying opened files when screen and key-
                         board are shut off and user has to restart
                         system using CONTROL+LEFT-AMIGA+RIGHT-AMIGA
                      Transient damage: Screen buffer manipulation:
                         screen becomes dark, keyboard seems to mal-

                         LEFT-ALT+LEFT-AMIGA (on newer AMIGAS, the
                         COMMODORE key)+SPACE+RIGHT-AMIGA+RIGHT ALT
                         (but virus will still be active)
Damage Trigger......: Permanent damage: reset; any disk access
                      Transient damage: only under following condition:
                         2 resets AND 6 infections AND execution of
                         BYTE BANDIT's own interrupt routine 5,208
                         times (approx. 7 minutes)
Particularities.....: uses StartIOVector; other resident programs using
                         the system resident list (KickTagPointer,
                         KickMemPointer) are shut down;
