PC Activity Monitor (PC Acme) is a powerful security program that tracks and reports all activity on your PC. It records not only all keystrokes, but all window titles and times, clipboard activity, and more. It records your computer startup and shutdown times, as well as the names of all running tasks. It runs invisibly. You won't see it on the task list, task bar, or system-tray area and has a minimal impact on system performance. The format of the log file makes it very easy to follow. Other features include automatic scheduling, log file encryption, password protection, and configurable filters. PC Activity Monitor is very easy to use and includes online help file.
