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!
