I've been using Google search engine for years on my imac which has OS 10.9.4. No problems. Two weeks ago, Bing replaced itself instead of Google as search engine. I changed my home page back ok. System shows Google selected as search engine, but even when I reset it to Yahoo or Google, this happens: Address line says "Search Google or enter an address", but when I type in a search and enter, the search gets taken over by Bing, and what I get is a Bing search. How do I get rid of Bing? Thanks for any help!
