You are today's Lucky Visitor....
Hello,
So today my niece was using my Iphone 5S, and this box popped up saying "You're today's lucky visitor. Press ok to take survey". It won't allow you to exit the webpage or anything like that. Without knowing better she pressed ok and then just closed the survey page. When she went back to the webpage she was at before the popup it all of the sudden opened the app store app. I know people have had this issue before but they didn't press ok. I was worried about it having downloaded a virus so I have factory reset the phone, but should I do anything else? Any recommendations, or do you think I'm safe having reset it?
Thanks
iPhone 5s
