Pop ups on Facebook and Safari
I'be been getting pop up ads, when clicking links on Facebook, links that I've clicked before and trust such as "9GAG" and "collegehumor". But t link keeps sending me to another website and then a pop up appears and says " you've won the newest iPhone, collect it now" and everything around turns slightly grey and have no other choise than clicking OK. But I have NOT done that, i've just restarted the app, but that do work, and now the same thing is happeni on safari.
DOes my phone have a virus? What should I do?
THanks in advance
iPhone 5s, iOS 9.2
