fbsetbg unistalled, but still on computer

[simon303]

Quite a while ago I messed around with Fluxbox as a window manager, and while doing this I installed fbsetbg to set a wallpaper.

I have since unistalled Fluxbox, but recently have decided to reinstall it, but I want to get rid of fbsetbg. When I try to remove it with apt-get it says the package can't be found, but when I try to install it it still can't be found. I know it's installed as I have found it in /usr/bin and can run it from a terminal.

Can anyone tell me how to remove it from the system?

Thanks

Simon
