I received and error message on safari that told me to call a 1-800 number-- otherwise the pop-up window would not go away. I did so and the man who answered said he was "Mike with Apple Support." I know this was [***] and immediately hung up. After that I repeatedly got phone calls from this number one after another after another from so called Mike who had a south asian accent. I told him to stop calling or i would contact the FBI and my local NYC police and he hung up. Be AWARE!
