This virus adds itself to the end of infected files and encrypts the full file after that.
Based on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the detected program or file, or ask you for a desired action.

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.
