But the better question is how did it get there in the first place?
I have had Fuse installed as a support utility for another application. I can't say which one of yours required it, but it can appear without directly and consciously installing Fuse.
Hmm, seems like another piece of "sneaky" software. Glad I use TechTool Pro for my disk repair/maintenance (after I have run Onyx), as I have never seen it.
