The Techiebyte: Predator

Imagine when you have to leave your desk for some important work , what you do to prevent someone from accessing your ongoing session. Well, you very well lock the computer by pressing window key plus L but there's a bettter way to that. Predator, a software which could blank your screen, disable the keyboard and mouse movement just by removing a flash drive. With just a USB Pen Drive, you could very well lock down your computer and to simply resume your work, insert it back. Incase you forgot your flash drive, simply punch in the password.

It's easier and faster than closing your Windows session, since you do not have to retype your password when you return.

Features:

PREDATOR can send alert messages by Email or by SMS.
PREDATOR records all security-related events in a log file: start, alarms, stop. By reading this log, you will know if intruders have tried to use your computer while you have been away.
PREDATOR can replicate this log on your Twitter account, allowing you to remotely monitor all access-control activity on your PC.
PREDATOR frequently changes the security codes recorded on your USB drive. If an intruder manages to copy your stick, this copy will not work because the codes on your own stick will have changed in the meantime.
PREDATOR disables the Windows task manager when you unplug the USB drive. Nobody can stop it with Ctrl-Alt-Del.
PREDATOR disables the CD Autorun feature in Windows, to prevent intruders from running malware on specially crafted CDs.
PREDATOR lets you regain control of your computer if you lose your stick: when you start the software for the first time, you set a password that will unlock your session if your USB drive is not available.
PREDATOR can sound an audible alarm if somebody enters an invalid password.
PREDATOR records all security-related events in a log file: start, alarms, stop. By reading this log, you will know if intruders have tried to use your computer while you have been away.
And finally, PREDATOR can protect several PCs with the same USB flash drive, e.g. your home and office computers.
