If you have a spare USB flash drive lying around, when combined with some free software you can use it like a key to access your computer.
The Program is called “Predator” and once installed it can make your USB drive just like the key to your car…the computer simply won’t work without it.
Plug your USB key into the computer and everything will run as normal, but the second you remove it the Prodator program disables all input, like the keyboard and mouse and it darkens the screen.
Should anyone try and access your computer during this time, the program will take note and let you know what happened…or sound an alarm.
You can download the Predator software HERE.
