How can I get rid of a Congratulations-you-won.com-yourprize.com pop up window on my iPad? It wants me to answer ok but I'm afraid it is a virus.

I'm getting this through facebook. Is there something on my iphone making this happen?

Highly unlikely if your phone isn't jailbroken. It's the link (to a website) in Facebook that is making it happen.

Hi, hoping that someone can help me. I have a similar problem as the topicstarter.

Currently have the following devices:

iPhone 6s, iOS 9.2.1, U.S. Apple ID

iPad Air2, iOS 9.2.1., Dutch Apple ID (recently moved from the Netherlands to the U.S. didn't change my Apple ID yet)

MacBook Pro retina, early 2015, OS X El Capitan 10.11.3, U.S. Apple ID

Now when I visit a certain website on my iPhone, ajax.network.to (from my favorite Dutch soccer club), I keep getting pop-ups that try and link me through to a website with a pop-up claiming I won something. I have been visiting this website on an near-daily basis without problems up until today. When I try and visit the same website from my iPad or Macbook I do not experience this nuisance. Same happens when in Facebook and I click through a link to go to a local Dutch news website (only that one!). Again, only happens on my iPhone.

iPhone is rather new (Dec. '15) and didn't jailbreak or anything. What could this be and how to solve it? Obviously tried erasing history/data, turning iPhone off/on. I want to keep visiting these websites and since I do not experience this problem on my iPad or with my MacBook I doubt that the problem is on the websites end?

Please help! Thanks in advance!!!

You have isolated the problem to your iPhone (other iOS devices do not experience the same pop-up problem). How do you access the internet on the iPhone, MacBook and iPad? Do you configure Safari browser exactly the same on all iOS devices (block pop-up enabled)?

Thanks for responding so promptly ShagCA,

Yes the problem is isolated to my iPhone. I do access the internet with all devices using Safari. Configurations are the same, so yes block pop-up is enabled on iPhone, iPad, Macbook. Do Not Track is enabled, as is Fraudulent Website Warning and I do Block Cookies except from websites I visit.

... are those devices accessing the internet through the same WiFi router? You can also clear Safari cache and disable WiFi radio. Retry accessing the same site through cellular network. Does the problem go away? I'd like to see if you can eliminate the router from the scenario.

We can rule the router out. All devices are connected to the same network. Just turned off Wifi on my phone. Cleared all data and history and visited the website and was again prompted with the problem. My wife doesn't have this problem on the same network with her iPhone / iPad / Macbook so somehow it really seems isolated to my iPhone ...

Hmm.. I agree. It sounds like something on that phone is triggering the pop-up. Did you say your wife's phone/ipad don't show the same symptoms when you use them to access the same website? Also be sure that those devices do not use ad blocker.

My next suggestion is start from the scratch. Backup iPhone to either your computer or iCloud. Do whatever you need to do to make sure you will not lose any photos taken with the phone. Then factory reset it. Do not restore from backup right away. Setup iphone as a new device then access that same site after resetting your phone. If the problem goes away, install the apps manually, one app at a time. Retry accessing the same website. Keep going until you can reproduce the problem.

ok so this is where it gets weird. It did happen when I visited the particular website from my wife's iPhone when I just tried. So it does seem to be this particular website but it only gets triggered by a U.S. mobile device (i.e. with U.S. Apple ID) and not before today ...?

I could try start from scratch but was hoping to avoid. Now that it did happen on a different device I'm not sure that it will solve the problem either. Aargh ... annoying people with their scams ...

By the way, when I disable Java-script it doesn't occur (makes sense since the pop-up would probably by a java-script?), when I browse in private it doesn't happen either and I can visit any other website (U.S. or Dutch).

So all this time you're saying your wife's phone isn't affected because you have never visited the same website using her phone? That makes sense. Now I'm thinking the website is the source of the problem. Have you contacted the website administrator to let them know about the problem? Btw, it is a javascript. It does nothing but annoys visitors.

That was so very helpful. Thank you. Simple and accurate.!!!

What if i filled up the questions from the free iphone 6s pop up message? What to do???

That depends. What information did you give them?

Had this issue with Google Chrome on iPad and was stumped. Airplane mode is not something I tend to think of. Thanks for the great simple solution.

Hi I have tried this several times. the thing is i use google and its on that page any suggestions please
