ad blocker

ad blocker

Software that eliminates advertising and other annoyances from Web pages. It detects banner ads by size (typically 60 pixels high) and by the URLs of major advertising sites where the images come from. Such utilities may also be able to eliminate cookies, referrers and animated GIFs, which are time consuming to download. See cookie, referrer, popup blocker and animated GIF.

Blocking Annoyances
The options panel from this earlier interMute utility shows the types of annoyances that could be eliminated from downloaded Web pages. The program acted as an intermediary between the user's browser and the Web. Trend Micro (www.trendmicro.com) later acquired interMute.
