How Does the USB Stick Lock and Unlock Your Computer

1. Predator locks down your computer when you remove the USB stick. It does not close any running instance – all the running process keep running. It just darkens the screen and the keyboard and mouse become inactive. When you return back and insert your USB drive the Windows gets unlocked automatically.

2. You can check the access log to know whether any person tried to access your computer in your absence. You can also setup an alarm system to get instant alert for unauthorized access. Predator uses the USB drive as an access control device. It does not perform any type of modification in the existing data in your flash drive. It keeps changing the security code record in your USB drive frequently. If any intruder copies your USB security stick it will not work because in the same time the code of your own stick changes itself automatically.

3. The Task Manager is disabled by Predator when you remove the USB stick. So no body can terminate any process in your Windows by pressing the keysAlt+Ctrl+Del.

4. If you accidentally lose your USB drive, you can unlock your PC with the password you set at the time of starting the software first time.

5. You can replicate the logs with your twitter account by remotely monitoring all the access-control activities.
