PC Spy lets you secretly monitor what is being viewed on your computer while you are away. It allows you to capture and save screen images while you are away from your computer, showing you exactly what was being viewed on your computer at specific times. It runs completely hidden in the background, as it is not visible in the task list when pressing CTRL-ALT-DEL, and all captured screens are not viewable with any normal viewer, but only with PC Spy. You simply select the start time, how many screens to save, and how often to capture the screens, and this is all done without any notice to the user. There is even a picture compression level to set which allows you to save disk space on captured screens.
