WHAT IS A KEYLOGGER?

Keyloggers are small spy programs, that record everything you type on the computer, including documents, emails, user names and passwords.A keylogger functions by grabbing a keystroke, triggered by when the slave presses a key on their keyboard, and saving it to a variable. This process is called "keyboard hooking". It then will take this long variable and send it via a SMTP or FTP server. You can then view these logs. 
It can come in many forms, as emails, viruses, Trojan horses; from people who might try to invade your privacy and see what you are typing or steel user names and passwords as you type them.
