Yahoo is taking over my Google search from my Safari on my Mac In Safari Preferences, Google is my Default Search Engine; New Windows and New Tabs are set to Homepage. 

However, recently whenever I Google something, I click on my choice and I end up on Yahoo Search.  Sometimes I get search.epolife.com.

This is very frustrating, I do not want to go to a new search of Yahoo, I like my Google. How can I regain control of Safari?
I found my answer in this YouTube video: how to get rid of searchbar redirect in safari.

In Safari's Preferences, select Extensions.  There was the epolife. I deleted the epolife extension, quit and relaunched Safari and came back in. After that I no longer have this problem.
