I called (855) 2268311 because on my safari it had said that my iPad was locked down because it detected a virus. The pop up then asked me to call this number. A man picked up and said he couldn't hear me so he hung up and called me back with the (510) number. He said I would need to pay $100 for him to fix the problem. I didn't and then cut the phone. Then I just canceled out of the pop up but I am not sure whether the iPad is still containing a virus!
