Do you know how they hacked your account? Part five: Keylogging

Keylogging  (also called keystroke logging) is a method that cyber criminals use to record (or log) the keys you strike on your keyboard in order to get confidential information about you.
Of course they do this in a concealed manner, so that you won’t know you are being monitored while typing passwords, addresses and other secret data on your keyboard as usual.

HOW YOU CAN GET INFECTED: 
Keyloggers are usually used with malicious intentions, to steal passwords or credit card information.
Although many anti-spyware applications can detect some software based keyloggers and quarantine, disable or cleanse them, there is no solution that can claim to be 100% effective against this type of threat.
