how to completely delete a program (macfuse)?

I installed macfuse last week but i didn't like how it worked so the other day i deleted the program by dragging the icon from the applications folder to the recycle bin. However, i noticed that there is still a macfuse logo in the 'other' section in my system prefernces menu. When i click it there is a message saying 'macfuse does not appear to be installed' and there is an option to install the program. I tried dragging the logo from the logo from the preferences folder but it doesn't work. Does this mean there are still bits of the programme i haven't removed from my computer, how do i get rid of this?

See Q 2.3 here. You are going to have to reinstall it to do a thorough uninstall.
