Use a USB memory device to block your PC

If you use a key to block access to your home or your car, why not do the same for the computer?

Predator turns any USB memory device into a key that blocks access to your computer. How does it work? Predator creates a special key in your USB drive, and then sits in the system tray while monitoring it. The key is renewed every few seconds for more effective protection.

The moment you leave your computer, simply unplug the USB memory device and your computer will be blocked: the screen will go black, and the keyboard and mouse won’t respond. When you’re back, plug the USB device again and Predator will make your PC go back to normal.

Predator is easy to use, though it could benefit from a bit more information about the program’s functions and a proper help section.

With Predator you can block access to your computer while you’re away with a simple USB memory device.

With Predator, you can lock and unlock your PC with a USB flash drive

With Predator, you can lock and unlock your PC by simply removing or inserting a USB flash drive. You can use any USB stick, the program will generate a security code and place it on the device to identify it as the key. It will then check every few seconds if the drive is still inserted and if it is not, the program will lock your computer and optionally take a picture with your webcam and email it to you.
