Norton Security causing Internet Explorer 11 to crash

As of today if I have Norton Security installed on my computer. Internet Explorer 11 will not open it crashes and says it's non-responsive and opens a Windows error reporting window and closes.

As soon as I run NRT, Internet Explorer works perfectly again.

What is going on? This is being caused by Norton Security. I tried all of the recommendations from Microsoft to fix this but none helped. I first got it to work by running system restore which removed NS. Then I ran NRT and installed NS again. After that IE11 stopped working. Now I've removed NS and IE11 works.
