Anybody know where I can find a keylogger? A good one?

[barbiegirls2]

Mom: i dunno much... looking for the best free hidden key logger to see what (Boyfriend) is saying to his internet girlfriends on myyearbook.com...
Me: Oh wow...

I took out names.
Anybody know any good key loggers that could help me here? Not carrying viruses that would actually harm the computer, just a good key logger. I'm sorry if this is in the wrong place, I didn't know where else it could go...
Help would be greatly appreciated.

If this is against the rules, feel free to delete the thread. And I apologize in advance if this is so.
