PEC Security Master is a simple but powerful computer-locking mechanism that keeps unwanted users out of your computer when you're not around. The software is incredibly straightforward--just set a password and activate the security at your leisure. Your keyboard will become locked and your mouse will be restricted until the specified password is supplied. In the event an intruder is unable to input the required password within the given time limit, he or she will then be locked out of the computer until you return, with a time stamp indicating when the intrusion occurred.
