Use text strings to identify ads to block or permit

You can control whether Norton Personal Firewall displays specific ads by creating a list of text strings that identify individual ad banners. Ad Blocking strings are sections of HTML addresses. If any part of a file’s address matches the text string, Norton Personal Firewall automatically blocks the file.

Norton Personal Firewall provides a predefined (Defaults) Ad Blocking list that is used to determine which images should be blocked when displaying Web pages.

When Ad Blocking is enabled, all Web pages are scanned for the HTML strings specified in the (Defaults) list. Norton Personal Firewall looks for the blocked strings within HTML tags that are used to present advertising. The HTML structures that contain matching strings are removed from the page by Norton Personal Firewall before the page appears in the Web browser.
