I bought a new iPad Pro for my wife 1 month ago, and she has been getting a message when using Safari that the iPad is infested with viruses. It states to download a VPN to fix the problem. The VPN app is described as downloadable from the Apple App Store but the URL is suspicious. Closing the message works only a short time before it reappears. Clearing "Website Data" in settings keeps it from reappearing - so far. BTW, the message states the viruses came from adult site, but I know that never occurred. A pic of the messages is attached. Is it spam?
