Whale

SIZE:9216
TYPE:Stealth Resident COM/EXE-files
REPAIR:No

Summary

This is a rather remarkable virus. It is long, 9216 bytes and able to infect COM and EXE files. The increase in file size is not visible though, while the virus is active in memory, as it uses several advanced "stealth" methods. Other effects of the virus are not known, but one infected program displayed the following message when run:

             THE WHALE IN SEARCH OF THE 8 FISH
             I AM '~knzyvo}' IN HAMBURG addr error D9EB,02


Most of the virus is devoted to encryption and code which moves blocks of virus code around. This overhead results in a considerable slowdown of infected systems, which makes any infection easy to detect.
