Koteyka is a joke virus on Microsoft Windows created by the malware YouTuber Enderman. It contains many easter eggs.

This virus is also a puzzle game mostly, the user has to find codes to get out of the thing and keep the virus secret.


When the maximum time is reached it says "Game Over" and a cat's face comes out on the user's screen.

On June 19th, 2018, the malware had a new design and the picture of the cat changes.
