                                     Number of       copys :'
Type of infection...: self-identification method: ---
                      system infection: RAM resident, reset resident,
                         bootblock
Infection Trigger...: reset (CONTROL + Left-AMIGA + Right-AMIGA)
                      operation: any disk access
Storage media affected: only floppy disks (3.5" and 5.25")
Interrupts hooked...: vertical blank interupt
Damage..............: permanent damage: overwriting bootblock, maybe
                         killing opened files when the screen and the
                         keyboard are shut off and the user has to
                         restart the computer using 
                         CONTROL + LEFT-AMIGA + RIGHT-AMIGA keys.
                      transient damage: screen buffer manipulation:
                         screen becomes dark, keyboard seems to mal-
                         function, transient damage may only be inter-
                         rupted by pressing a special key combination:
                         LEFT-ALT+LEFT-AMIGA (on newer AMIGAS the 
                         COMMODORE key)+SPACE+RIGHT-AMIGA +RIGHT ALT 
                         (but the virus is still active)
Damage Trigger......: permanent damage: reset
                         operation: any disk access
                      transient damage: only under following condition:
                         2 resets AND 6 infections AND execution of 
                         BYTE BANDIT's own interrupt routine 5208 times
                         (about 7 minutes)
Particularities.....: uses StartIOVector
                      other resident programs using the system resident
                         list (KickTagPointer, KickMemPointer) are shut
                         down
