Found some terrific information about blocking ads in Internet Explorer. IE has an option called Tracking List Protection. To access, open up Internet Explorer, go to settings (gear icon in upper right corner) and then click Manage Add-ons. In the list of Add-On Types is an option called Tracking Protection.
Click Tracking Protection. Towards the bottom of the screen is a green arrow that points to Get a Tracking Protection List online… Click and it will take you to the Microsoft add-ons page.
Several different Tracking Protection Lists are available. Click Add on the ones you want, and then close and re-open your browser.
