ctrl-alt-del is not a program but a magic key sequence for x86 machines to get attention of the kernel to do something, which defaults to safe reboot on most recent linux distributions. On WinNT it is used as a Secure Attention Key during login. More on key mappings can be found in Keyboard-and-Console-HOWTO and /usr/src/linux/Documentation/SAK.txt
