Advertisements and Pop-ups

This category includes sites of banner ad servers, sites with pop-up advertisements, and sites with known adware.

Important
Blocking Advertisements and Pop-ups also blocks content that appears behind interstitial pages, pages of advertising that appear prior to the loading of a requested content URL. In blocking these pages, the content that is behind them is also blocked.
Note
Sophos's advanced categorization data uses the most current technical definition for Adware, and thus recognizes the difference between non-malicious adware, such as "cookies" and more serious Spyware.
