Scary.exe is a screamer application which runs on Windows computers. The icon has a skull with a large black eyes with a yellow border in his head. When launching the application, a window named 'Time configuration' appears, in which the user can choose in how much seconds the screamer will show, with the default being set to 60 seconds. After the time has passed, a picture of Regan MacNeil from The Exorcist appears, along with a loud lopping scream. In the upper left of the screen, there is a X button which closes the screamer.
