How to stop Google Search Redirected to Bing

All my Google searches switch to Bing, even though Google is the default search engine in Safari preferences. This started several days ago (Dec 30, I believe) when I tried to download a movie from the French TV site, TV5.

I went to my applications. I did have an application that was downloaded that day. I put that application into the trash, but I have not emptied the trash and could recover that application.

I did notice in the Safari preferences that the Search engines listed are now 1. Google, 2.Yahoo, 3. Bing and 4. DuckDuckGo. I assume that DuckDuckGo is an emerging search engine.

A Symantic scan did not find anything related to this problem.

There is a "search.strtpoint.com" statement that appears and redirects my Google search to Bing. I was able to copy and paste the statement to a text file. The total statement is: http://search.strtpoint.com/results.html?c=35&v=insMac&t=1412&ap=97963554&r=ab3c cf12be2240f5a0926c759fb396c0&spt=ext&q=

Any ideas on how to eliminate the redirect statement?
