This morning I was reading some news on some websites (I think one of them was haaretz.com) using my iPad (ios 9.0.1), I clicked on a news and I was redirected to some dodgy website and I started getting all kind of popups. I killed the tabs but I keep getting these popups and auto-opened tabs on all the browsers (even facebook app)
How can I remove these? How dangerous do you think they are? At the moment it looks like it's a form of malicious advertising for all kinds of things.
EDIT: Cleared both history and website data, rebooted iPad, visited only bbc and the pop-ups are still appearing
