I think this is a bad process. My mouse wasn't working, until I stopped this process in Windows Task Manager. Delete process, if you see that it's running

On my 64 bit Win 7 this file is located at: C:\Program Files (x86)\Bonjour

Like many Apple startup programs for Windows, this is a fairly useless program as Windows does all of the things it suggests to do, by itself. It is invasive, hard to remove, and takes up resources. It is also suspected as being spyware due to packets sent out.

Too Slow for XP drags the system down!

It is for Apple iTunes, and other apps (not necessarily Apple.)

mDNSResponder.exe is a spy program used by Apple to spy on its customers and send information to Apples massive database on the activities of its customers. It is malware.

Apple Bonjour (Redezvous) allows you to use a network without any configuration, widely used in MacOS and Apple products, but also has a Windows version and may be included in other software not produced by Apple such as Adobe Photoshop.
