--------------------- Attributes -------------------------------------
Easy Identification.: typical text: bootblock: ---
                             in memory: 'The LAMER Exterminator !!!'
Self-identification.: 25th word on bootblock is $B3BEB2BB; kicktag
                         pointer points to virus code
Type of infection...: System infection: RAM resident, reset resident,
                                        bootblock
Infection Trigger...: reset ( CONTROL + Left-AMIGA + Right-AMIGA );
                      any disk access
Storage media affected: floppy disks (3.5" and 5.25")
Interrupts hooked...: ---
Damage..............: Permanent damage: overwriting bootblock;
                         simulation of standard bootblocks when
                         examined with any tool;
                         fast-formatting disks.
                      Transient damage: allocates 1024 bytes in RAM
Damage Trigger......: Permanent damage: reset; any disk access;
                         virus action after 6 resets and 3 infections
                      Transient damage: ---
