Programs designed to monitor user activity. They may be used with or without consent. Because it is sold commercially, many anti-virus vendors do not detect them. The most common form of a commercial monitoring tool comes in the form of a keystroke logger, which intercepts keystrokes from the keyboard and records them in a log. This can then be sent to whoever installed the software, or keylogger, onto the machine. Some Commercial Monitoring Software may take screenshots or video and send the information to an outbound connection.
