Recommended Keylogger Detector Softwares?

Hey guys, I was wondering if any of you computer veterans can recommend me to a trustworthy key-logger detector software. I tried googling for one but I'm paranoid I'll get one myself for randomly clicking.

Thanks.

As for me, I'm still okay with no antivirus, and use only common sense. AVG is a worthy tool for most issues, by the way.
