Add address to the Intranet Zone in IE using code

I need to add a URL to the list of trusted sites in my Intranet zone.
I'm looking for a way to this automatically, in order to save my users the need to configure it manually.
Is there a way to do this from code? I have an ActiveX running on all of their systems, so I can add the code to it, if it's possible.
