From SoftDD Software:
Secretly monitor what is being viewed on your computer while you're away. This software allows you to capture and save screen images, showing you exactly what was viewed on your computer at specific intervals you can set. All screens can be captured, including chat windows, e-mail windows, Web pages, and anything else shown on the monitor. PC Spy runs completely hidden in the background, and all captured screenshots are viewable only with the PC Spy software. You simply select activate
and how often you wish to capture screenshots, and the software will begin working without any notice to the user. You also can set a start time if you want the software to sit dormant and begin capturing only at a later time, and there's even a graphical compression level you can set, which allows you to save disk space on captured screens. This software also can be activated from a diskette or USB, leaving no trace of the software on the computer.
