Horrible

I just downloaded the update on April 19th 2016 and now I cannot search the web. The only pages that open up are Apple Inc pages and iTunes. Every website that is not apple says cannot connect to server. It does not matter if I use Safari, Google Chrome, or Firefox, they are all giving the same result. This is so frustrating as I have a lot of work to do and I do not know how to uninstall to get back to the older version. My internet connection is fine the only thing that has changed is me downloading the new update. please help. Fix this thing asap.
