Is this for real or a scam?
I just had a big window come up on my screen.....a voice said that a virus had infected my computer and I should not shut it down....there was a phone # to call Apple Support but I didn't.
I signed out of Safari and the message is gone.
Then I got a message on my iPhone a minute later sayin "Your Apple ID is being used to sign in to a device near Kirkland WA"
What should I do?
