Sometimes it's necessary to keep track of the computer use for a number of reasons, like a company wants to know how its employees are doing at work, or a parent wants to know how their children are using their computers, and you want to see what others are doing on your computer after you leave. This is where software like the keylogger (keystroke logging) comes in. But you'd better not use it for illegal or unethical purposes!

Master Keystroke Logger is a keyboard keystroke recording program. It has at least two applications: 1) Install it on your own computer, so it lets you know if someone did something on your computer and sends an email notification when you're not there; 2) Install it on someone else's computer as a hidden computer activity monitor.
