Fbi warning files encrypted?

I was on my Iphone browsing when this window popped up that my files had been encrypted and the fbi has been alerted and that I violated these laws it was not from fbi.gov it was from.net address so I thought it was fake. Should I be worried or was it fake?

It's fake. Ignore it. If you had broken a law they certainly wouldn't tell you that the FBI had been alerted.

Fake

Sounds fake. I bet they wanted you to do something to alleviate the situation.

I got a similar message but at the top of the message it says Data://(null) , that means invalid should I just ignore it?

How did you get the pop up to go away mine just did the same thing.
