Bonjour is an Apple networking utility that often gets installed with itunes and even adobe products.

If aford10's revo uninstaller doesn't do the trick then try these manual removal steps:

1. Go to Start->Run and type CMD and press the Enter Key. Type the following command:

"C:\Program Files\Bonjour\mDNSResponder.exe -remove"

2. Navigate to the following folder: C:\Program Files\Bonjour

3. Rename the mdnsNSP.dll file in that folder to mdnsNSP.old

4. Restart your computer

5. Delete the the C:\Program Files\Bonjour folder
