Details of Bonjour as follows:

Systems use Bonjour primarily to facilitate the installation, configuration, and use of network printers, and thus it runs from startup. When it is fully implemented on MS Windows some features such as iChat allow for communication between the Mac OS and MS Windows.

Bonjour also comes bundled with some third-party applications, such as Adobe's Photoshop CS3 suite. Installers on Windows systems normally place Bonjour files in a folder called "Bonjour" within the "Program Files" folder. It modifies Windows system-registry entries related to internal network configuration and operation. It runs as mDNSResponder.exe. Communications across the network take place over UDP port 5353, which may require reconfiguring some firewalls that block Bonjour packets.
A full installation will include a plug-in for I.E., a printer wizard, and the network communication services. Not all components are included when installed as part of a third-party application or as a component of other Apple software such as iTunes. Some VPN clients are configured so that local network services are unavailable to a computer when VPN software is active and connected. In such a case no local Zeroconf services are available to Bonjour or any other Zeroconf implementation. The open-source IM clients Pidgin and Kopete support the Bonjour IM protocol, as does the non-GPL Trillian client.
In the past years two security vulnerabilities were found in Bonjour for Windows. Certain installations of Bonjour for Windows lack an uninstaller and do not display a human-readable entry in the Windows services listing. In 32 and 64 bit releases of Windows 7 the Bonjour service can disable all network connectivity by adding an entry of 0.0.0.0 as the default gateway. The work around is to disable then enable the system NIC (ethernet card) in Windows' device manager but the only permanent solution is to disable the Bonjour service and remove the offending software.

Hope I can help you.
