Burger

SIZE:382-560
TYPE:Non-resident Overwriting COM-files
REPAIR:Impossible

Summary

This virus should not be a serious threat - like all other overwriting viruses it does not survive in the wild for any significant period of time. Nevertheless, it has been reported a few times - possibly typed in each time from the book by Ralf Burger where it was originally published. At least eight 560 byte variants are known, but they are all of equally little interest. They are named Burger 560-A, Burger 560-B etc.

VARIANT:Burger 382
ALIAS:382 Recovery
A shorter variant originating in Taiwan.

VARIANT:Burger 405
ALIAS:405
This variant contains a minor error, which prevents it from recognizing the files it has already infected, so they are overwritten again and again.

VARIANT:Pirate
ALIAS:Lima
A 609 byte variant, containing a message which indicates it was written in Portugal.
