Since updating to iOs7, every now and then opening Chrome causes my router to display a message (on iPad screen) that the place my browser wants to go is potentially dangerous. This activity results in the iPad turning WiFi OFF, in turn, forcing me to go to Settings and turn WiFi on, again. What are the chances I've stupidly picked up something dangerous? Please don't suggest running only Safari unless that's the only solution. I'm not suggesting the problem's related to updating; it's just one of the things that happened.
