What is a Key Logger

The link here shows a little device that fits between a computer and a keyboard. It can be used with a PC or a Mac. And it captures every keystroke. The concern? You are on a public computer somewhere and someone may be spying on everything you type, the websites you visit, your user names, and your passwords. The spy doesn't need to install any software, just unplug the keyboard and insert the device inline. My point is that you need to be careful! A key logger can also be software that is installed on any PC or Mac. You can check your computer with the software here (designed for Windows XP but may work with other Windows versions). If the program detects a key logger, you might try the program here to remove it.
