Help FBI WARNING ON MY IPHONE?

I was browsing on my phone and an fbi warning popped up, telling me to pay a 500 fine or my phone will be shut off. I can't get rid of the virus on my phone. If I get out of safari it keeps popping up and I can't do anything. SOME Please I'm NOT CALM RN. How do I get it off my phone without using money?

It's a spam thing. Don't pay money because they will take everything in your bank account. Just restore your phone and just use iCloud and you will get your stuff back!

Force quit Safari. Then hold Shift down when starting it again. (You could probably go into Preferences, if you can, and temporarily disable Java, to have the same effect. This malware works via Javascript.) This will prevent any web pages being loaded. Next Reset Safari and and Empty Cache from the Safari dropdown menu.

It's a scam. Never pay money to anything like this, you're just giving it to criminals and you'll still have the problem.
Force Safari to close. Go to Settings ->Safari-> Clear all history and cookies. Reboot your phone and it should be clear.

Download the free version of avast anti virus.it has a free gadget for your phone as well… Download it on a pc then transfer the gadget to your phone… Cheers

Thats just a fake webpage. Search and you can find info on it -> http://www.justtext.com/messageboards/20150810172534.html?y85f There are alot of people complaining they are getting these popups

Clear the Safari cache in Settings > Safari.

Factery reset

It's a scam. Ignore it. Normally these scams come from China because that is where a lot of the malware originates.
