A pop-up appeared while on safari with a toll free number. It said, "Warning! Apple Security Breach! IOS Security Crash!" Then it tells me to contact this toll free number 1-844-749-1071 for assistance immediately. Is this a scam?

Double click the Home button and swipe Safari upwards. Go to Settings/Safari and clear History and Website Data. Open Safari and test.

Safari - Clear the history and cookies on your iPhone, iPad, or iPod touch

Safari website data on your iPhone or iPad - How to clear

Safari - Stop pop-up ads in

It is a scam, exit Safari and start it with the shift key held down.

I got this one, and they charged $39 when I called through Skype. I didn't comply to their fraud scheme but I gave them my name and phone number unfortunately/unscrupulously. I could clear away this pop-up window by clearing the history in setting > Clear History and Website Data.

Actually one idea, try a phone reset.

Reset iOS 6 Settings. To reset the settings on your device go to Settings >> General then scroll down and tap the Reset button at the bottom. On the Reset screen tap Reset All Settings – Not Erase All Content and Settings – then you'll need to verify you want to do it twice.

The easiest way to resolve this is to close Safari by double tapping the home button. Go to settings -> Safari -> Clear History and Website Data. This will then return Safari to it's original settings and resolve the issue. Hope this helps.

I just had a flashing warning sign that said security breach call 866-339-7833. I called the number and it sounded like a busy call center in the background. A man with a thick accent took my call. I asked what is the name of the company he works for. He told me he was in technical support for Apple. I asked him "how do I know that this is really apple. The man got very combative and asked me "how do I know who you are and just went off on me. I tried to cancel the call but the warning sign kept flashing and wouldn't let me end the call, so I turned off my iphone. I then immediately contacted apple. If the guy was really from Apple, I think he would have known who I am by asking me security questions. It has to be a scam. I'm hoping that by calling the number provided, I haven't set myself up for a virus. Any input on this thought?

Afraid I don't know about iPhones, you never mentioned it and this is a Mac OS forum so I assumed that you used a Mac.

Maybe someone who does know will come by.

This worked for me. Thanks so much!

Worked for me also so thx

You are welcome.

Settings -> Safari -> Clear History and Website Data

i would also power off, wait about 10 seconds, then power on.

I recommend the power off for any IOS or OS X system.

Worked first try, very helpful!
