Yes. This is possible. We can make an intermediate device to catch and record all keystrokes before entering to the PC. If you study the PS/2 protocol, you will notice this is very simple to make.

Anyway you can prevent from those by using you brain

when you typing a password (or any secret text), just type half of your pword in the correct place, then type some charactors on another place and type other half of pword in correct place. Then anyone unable to track your passwords by this trick.

Very nice advice Rksk.
Actually it may be correct.
But,some time this is not good.hacker can get our password using time which we typed password and other character and using place of typed.
But,hacker must know our trick.
