Keylogger is not a type of malware, but rather a simple program which capture all actions taken on a computer. This software is designed to record all keyboard strokes taken, mouse clicks and any other movements which are made while the PC is running. Keylogger, more commonly known as keystroke logging or key capture, is the act of capturing the keys struck in a keyboard, usually covertly, so the user who is using the computer is not aware that their actions are being recorded. The captured keys can then be used by the user of the capture program to bypass any security applications and access sensitive information on the system. Many times, these keystrokes are used to obtain the password of the system. Keylogger programs also capture screen shots, which are later displayed to the intruder on the PC.
