Psm Anti Keylogger
http://psmantikeyloger.sourceforge.net
Open Source
I did see some less serios tools in Closed Source. But this here seams to work very well. It could be a nice addon to travel with. Sure it can`t be perfect and unbeatable but I think it will detect 99% of public available keyloggers.
Could some Delphi programmer review the code?
