You can download ClearLock 2 1.4 from our software library for free. The program belongs to Security Tools. The actual developer of the free software is Swan River Computers.
From the developer:
ClearLock is a transparent screen locker aimed to make the computer tech/system admin's live easier by providing a way to disable input to a computer while still allowing you to see what is going on.
ClearLock is not a security system. Its purpose is to keep meddling users from screwing with the computer when you are fixing it. It will not keep your computer/data safe from someone who is determined to get at it.
