LamerExterminator is an boot sector virus on the Amiga operating system.


When a disk infected with LamerExterminator is booted, the virus will load itself into memory. It will install itself to any disk that is accessed. The virus is encrypted, and if it is not in memory, it will show the encrypted virus when the boot sector is read. If the virus is in memory when the boot sector is read, it will show the original clean boot sector.

LamerExterminator has a damage routine that will activate at any reset or disk access. It overwrites bootblocks 84 times with the string "LAMER!". This will cause a read-write error n the disk.

LamerExterminator gets its name from the text contained in the viral code. It is sometimes also called "Lamer", partly because LamerExterminator is an unusually long name for a virus and also because it overwrites bootblocks with "LAMER!".
