Products of the PC Activity Monitor™ (PC Acme™) line are designed for invisible and undetectable monitoring of PC users' activity. PC Acme™ software works under Windows 2000/XP operating systems. All the data collected by the program module for invisible monitoring, called "agent", are saved to the hidden encrypted log file located on the machine under monitoring. The monitoring agent works in the background transparently for the user, on the level of OS kernel driver. All PC Acme™ surveillance products support UNICODE, i.e. they are able to capture information written in languages with hieroglyphic writing, like Chinese. PC Acme™ computer monitoring software products are well-protected against anti-monitoring tools. They are completely invisible, and even an experienced user cannot locate, stop or destroy this monitoring program. Information from the invisible log file after it has been decoded and processed, is entered to the database. Reports from the database are converted into HTML format.
