Predator is a Freeware PC Locking Tool created by Richard Goutorbe. It can be used to securely lock your computer “while you’re away”, protecting it from prying eyes. Once Predator has been installed on your PC and your USB Key prepared, simply remove your Flash Drive to lock the computer. The computer can be be unlocked by re-inserting the Flash Drive and typing the password you set to unlock it. Predator will also log all USB login attempts, so you can see if anyone has been trying to get into your PC.
