Ideas Permissions, Search Results, and /ideas/ideaList.apexp

How do I make this: /ideas/ideaList.apexp not be public? How can i edit that? I removed all profiles able to view IdeasHome, however I can see still that ideas list.

Also, when searching from that page, it returns hits on the Files object, which I'm unable to remove. The Files tab is hidden.

Please advise! Thanks!
