Just passing on this info. I had been having issues with Internet Explorer 11, Windows10 for the past few days. IE would only load for a second then close. In add/remove problems I had a program I had not installed named 'Cash back assistant' from capital intellect. Norton deemed this a safe program so I left it in place. After two days on trying to remedy the issue I decided to remove the program and all my IE issues went away. I think Norton should take another look at this as it seems to be a pretty big issue considering all the talk in the problem solving community.
