ksLogger monitors all keystrokes made on the computer and sends them to a log file. You define the location and name of the log file. The program is hidden from the tray, so you don't know it's running. The process is named sys007s, so it looks like a system program when it's running in the background/hidden. You also have the option to capture the captions of all visible windows, so it's easy to monitor what programs are running.
