--------------------- Attributes --------------------------------------
Easy Identification.: typical text: --
                      virus feature: 'VKILL 1.0' requester before
                         opening CLI and detecting a virus or a non-
                         standard bootblock (see below)
Type of infection...: self-identification method: ---
                      system infection: RAM resident, reset resident,
                         bootblock
Infection Trigger...: reset (CONTROL + Left-AMIGA + RIGHT-AMIGA)
                      operation: on bootable standard bootblocks:
                         any access on bootblock sectors (blocks 0,1)
                         created using normal file system and new fast
                         file system;
                         on nonstandard bootblocks: when detecting a
                         virus or a nonstandard bootblock AND
                         'VKILL 1.0' request AND positive answer
Storage media affected: only floppy disks (3.5" and 5.25")
Interrupts hooked...: ---
Damage..............: permanent damage: overwrites bootable standard
                         bootblocks; simulates bootable standard boot-
                         blocks when examined with any tool
                      transient damage: screen buffer manipulation:
                         'VKILL 1.0' requester before opening CLI and
                         detecting a virus or a nonstandard bootblock
                         (see below)
Damage Trigger......: permanent damage: reset
                         operation on bootable standard bootblocks:
                         any access on bootblock sectors (blocks 0,1)
                         operation on nonstandard bootblocks: when
                         detecting a known virus or a nonstandard boot-
                         block (see below) AND 'VKILL 1.0' request
                         AND positive answer
                      transient damage: when detecting a known virus
                         or a nonstandard bootblock (see below)
Particularities.....: a resident program using the CoolCaptureVector is
                         shut down; detects BYTE BANDIT, SCA (and SCA
                         clones) and nonstandard bootblocks; detects
                         standard bootblocks of the new fast filing
                         system ('DOS' + $01); virus encodes itself
                         using ascii characters ' Ken' as key
