The Manage Search Engine List has an option to remove an entry, however when I remove About.com, it is back the next day. How do I permanently listing from this list? Removing a search engine 1. Click the search engine icon and select Manage Search Engines..., to open the Search Engines Manager. 2. To remove a search engine, select it from the list, and click Remove. Doing the above dose removed the selected entry (about.com). However the next time I start the computer About.com is back on the list.
