What is a Keylogger Trojan?

It is a digital version of the ancient "trojan horse" deception: fool people into welcoming a nasty program onto their hard drives. Disguised as legitimate commercial software or an innocent-looking file attachment, a trojan keylogger will wait for you to install it. Then, the keylogger will perform its dark deeds by recording your keystrokes and stealing your passwords and private login information.  Don't get keylogged... teach yourself how keylogger trojans work.
