Fatal Error - Version 1.1 Fatal Error is a small but nasty little joke program. When run, it displays a message box that says "Warning... Your system has become unstable!" and confronts the user with three choices: "Abort," "Retry," and "Ignore." Each of these three choices displays one of three equally frightening error messages... "Erase All Data on C: ?" "Format C: ?" or "Delete OS?" Put this in the unsuspecting victim's Startup folder and watch them squirm!
