I keep getting this

The current webpage is trying to open a site in your Trusted sites list.  Do you want to allow this?

To turn it off, open your browser, go to Tools > Internet Options > Security > select Trusted Sites > click Custom Level to view the browser settings. "Websites in less privileged web content zone " could be set to prompt. You may want to change the setting to enable or disable instead.
