Welcome to AO!

depending on the type of keylogger, it might be detected by some of the common anti-spyware programs [ie adaware, spybot search and destroy, prevex1, etc] .. try searching for keylogger detection ... also try running 'netstat -a -b' from a command prompt ... ( start > run > cmd ) [sorry if it seems I am talking down to you, but I have no idea of your technical knowledge] this should show you your active connections, and the executable responsible for the connections... hope this helps
