|Bonjour is part of iTunes. It lets your Apple device interact with other devices on your computer such as printers, etc. If you have an Apple device connected to your computer such as an iPod, iPad, iPhone, etc, keep it.|
PS. Bonjour is a French word, it's a greeting. Fingers was trying to explain to you that you may have a problem Googling it since it would come back as more of a definition of the word and not what the program does.
