How can I get viruses off my iPhone?

Your phone has no viruses. For all practical purposes iPhones cannot get viruses. You got a message that was a SCAM from a criminal hoping you would respond to it and provide personal information so your identity or your money could be stolen. The message may have looked like it came from Apple, but it didn’t. It came from a criminal.

Your phone doesn’t have any viruses. Why do you think it does?
