Removal



Automatic Disinfection

Technical Details



When run, the virus decrypts the original program and writes it to the file called HOOTERS.EXE. Then it executes this file and finally deletes it - sometimes leaving a zero byte HOOTERS.EXE behind.

A side-effect of this is that the memory map might list - for example - an infected mouse driver as HOOTERS.EXE instead of MOUSE.EXE.

Hooters was found in the wild in Australia in September 1996. It has been spread over the internet.
