Hi Andrew,
I see know! I though it was about this Silk UI Sample Pages component.
What you can do in your case is to disable the App that have the module Web Patterns.
This can be done in ServiceCenter on the Application detail screen:
This way when you access the HomePage of WebPatterns you will get the following page:

Don't worry because this will not affect any of your consumers modules, it will only restrict access to screens.
Any way this link will not stop to appear in your Scans.
For it to happen I imagine you would have to try to stop this app in IIS.
Maybe you would need to create a different application pool, put this module in there, and stop it.
But I'm not sure it would not create other issues and solve 100% your problem.
Cheers and Regards,
RR :)
