Hackers usually use keyloggers to steal your online accounts when you login to online services (Facebook, Gmail, forums, games, etc.). It's not easy to detect keyloggers because they are hidden and run in background.
Keystroke logging (more often called keylogging or "keyloggers") is the action of tracking (or logging) the keys struck on a keyboard, typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored. It also has very legitimate uses in studies of human-computer interaction. There are numerous keylogging methods, ranging from hardware and software-based approaches to acoustic analysis. (http://en.wikipedia.org/wiki/Keylogger)There are 2 kinds of keyloggers: hardware-based keyloggers and software-based keyloggers (http://en.wikipedia.org/wiki/Keylogger). The free anti-keyloggers mentioned in this post only work with software-based keyloggers.
