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

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.
