Alias(es)...........: ---
Virus Strain........: LAMER EXTERMINATOR Strain
Virus detected when.: October 1989
              where.: Elmshorn, Germany
Classification......: Encrypting System virus (bootblock), resident
Length of Virus.....: 1. Length on storage medium: 1024 byte
                      2. Length in RAM           : 1024 byte
--------------------- Preconditions ----------------------------------
Operating System(s).: AMIGA-DOS
Version/Release.....: 1.2/33.166, 1.2/33.180, 1.3/34.5
Computer model(s)...: AMIGA 500, AMIGA 1000, AMIGA 2000A, AMIGA 2000B
--------------------- Attributes -------------------------------------
Easy Identification.: typical text: bootblock: ---
                             in memory: 'The LAMER Exterminator !!!'
Self-identification.: 506th word on bootblock is $ABCD; 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; over-
                         writing blocks 2-3 where old bootblock is
                         stored, so uninstalled disks may be infected;
                         simulation of standard bootblocks when 
                         examined with any tool, by manipulating disk
                         read pointer; destroys blocks by overwriting 
                         them with 256 random numbers.
                      Transient damage: allocates 1024 bytes in RAM
Damage Trigger......: Permanent damage: reset; any disk access;
                         virus action after 4 resets and 2 infections
                      Transient damage: ---
Particularities.....: Uses StartIOVector; other resident programs 
                         using system resident list (KickTagPointer,
                         KickMemPointer) are shut down; virus encodes
                         itself at every new infection (Bytes 42-1008)
Similarities........: LAMER EXTERMINATOR virus strain
