How to stop Bonjour?

A few weeks ago Windows Defender started giving me the message "a system change has been made by a known application - C\Program Files\Bonjour\mdnsNSP.dll". I don’t want Bonjour running soI uninstalled it via the Control Panel. It disappeared from the Uninstall/Change Programs List, but still continues to run. I disabled the Bonjour Service, but it still continues to run. I executed the following two commands:

“%PROGRAMFILES%\Bonjour\mDNSResponder.exe” –remove

regsvr32 /u “%PROGRAMFILES%\Bonjour\mdnsNSP.dll”

- the first was confirmed as successful, but the second gave no confirmation of any kind. I tried to delete the Bonjour folder but was told that I can't delete mdnsNSP.dll because the file is open in another program. I stopped it using Task Manager, but it still continues to run. I'm running Windows Vista Home Premium. How do I stop Bonjour running, so I can delete it?

Windows Vista

Is the Bonjour Service still showing up in Services? If so, we can try disabling the service in there.

In your Start menu, right-click Computer and select "Manage".

Expand "Services & Applications".

Open "Services". (Perhaps maximise the screen to better see what's going on.)

Right-click the Bonjour Service and select "Properties".

In the General tab, set the Startup type to "Disabled":

... and click OK.

Restart the PC. Are you able to delete the Bonjour folder in program files now?

No, it doesn't show up in Services. I did disable it there, but after I executed the two commands I indicated in my original post it disappeared from Services altogether. So it doesn't show in Services, the Uninstall/Change Programs List, or Task Manager.

Doublechecking something. Is the Bonjour Service currently appearing in the Services tab in your MSCONFIG?

No, it's not listed under System Configuration Services tab either.
