Since we are on the topic of keyloggers...
Just for fun, look at the back of your machine for any hardware based keyloggers.
To see what one looks like, go to google, click on the 'Images' link
and type in Hardware Keylogger. That will show you pictures of one of the more
commonly used types.

errr... while highly doubtful, there is always the possibility that IF a hardware keylogger
was used, it was built into the keyboard itself.... but as I mentioned... doubtful. That
would cost quite a bit more $$$ and is seen more-so in government related environments.... and even then, not that often.

*If you did find one by chance, I'd take it/hide it and see how odd the guy acts when he finds it missing. LOL*
