Remove Android file transfer

I've just been to my "least used apps" screen using Launchpad and was taken aback to find a little green man there. His name is Android file transfer; I didn't invite him in and he never had the courtesy to ask if you could come on board. I want rid of him, permanently.

And that's where the real trouble starts. He doesn't show up in my Applications folder, but is identified as an Application when I do a Spotlight search. CTRL Click launches him without providing the option of deleting, and he just bounces back when dragged to the trash.

Please can anyone tell me how to kill him off, and, even better, tell me how to stop him coming back?

Thanks
