Cookie, also known as Cookie Monster is a boot sector virus for the Atari ST.
When a disk infected with Cookie is executed, the virus becomes memory resident. Each time a disk is inserted into drive A, it will become infected. In the original, version, the virus can be removed from memory by a simple reset. There is a second variant that is exactly the same as the original except that it can survive a reset.
After 30 copies have been made, and after every 20th copy after that, it will write "YOU KNOW WHAT? I WANT A COOKIE!" onto the screen. It will then wait for the user to type "COOKIE", not allowing the user to do anything until entering the word.
It is one of a few different Atari ST viruses released by "The Lazy Lion", a coder from Norway who seems to have done little else of note, at least under that name.
