Get rid of Type Agent

Hi, does anyone know how to get rid of Type Agent? I found it in the application folder, it's recording probably everything going on in my computer, and I could not find a way of uninstalling it (if I put it in the trash it comes back)! By the way I found an uninstall folder, but could not open it (says that there is no application to open it, would you know which application is needed to open it??)
Thanks a lot!

Type Agent is a keylogger, perhaps you need to investigate how it got there...

Put it in the trash and empty it immediately?

You'll probably have to reboot and log in as root to remove it.

Thanks, but what does it mean to log in as root (I am in France, so I am looking for translation, is it like administrator?)
