The only thing I know about Bonjour is that I had to uninstall it every time after installing iTunes on my PC.

I used to do that too because I didn’t know what it was or why I would want it. Now I intentionally have it installed without iTunes since its so handy.

Chances are it's installed right now. It's bundled with so many things.
