Ever since I upgraded to IOS 7, I have been having this annoying problem. When I click on a URL it opens the page that it is supposed to open, but then seconds (1 to 45) later opens the app store to a random game putting the page in the background. I can close out the app store and click the page again but it re-occurs. This happens on my iPhone 5 and iPad 4, although it does not happen every single time I click on a URL, but it does happen quite often. My iPhone is currently setup to use Safari by default, but I tested it in Chrome and it happens on it as well. I figure it has to be ads opening the app store, but have no proof of that. Any suggestions and or ideas welcome, heck if I could get a general direction to fixing it, that would be great.
