Hi,
Bonjour is Apple software and for further information ask in their Community..

Q. Why do I have Bonjour on my Windows system?
If you didn't install Bonjour for Windows manually, the most likely reason is that it was installed by an application that relies on Bonjour functionality. For example:
- iTunes uses Bonjour to find shared music libraries, to find AirPort Express devices for streaming music to, and to find Apple TVs.
- Safari uses Bonjour to find devices advertising web pages on your network. Many of today's network printers, network cameras, and wireless gateways provide a web interface for status and configuration, and many of these devices (especially network printers) now advertise those web pages using Bonjour, to make them easily discoverable in Safari.
- Internet Explorer, via the Bonjour toolbar plugin, also provides easy discovery of Bonjour-advertised web pages.
- The Bonjour Printer Setup Wizard uses Bonjour to discover and set up Bonjour-advertised network printers.
- Adobe's Creative Suite 3 applications use Bonjour to discover digital asset management services.
Cheers.
