How to get rid of "Trojan spyware" popups that seem fraudulent
I get three different types of popup messages interrupting my work from time to time, claiming—one in a very suspicious-sounding voice—that my Mac has been invaded by "Trojan spyware." They want me to follow links that they supply or call so-called Apple Support on a supplied phone number. How to get rid of these? I've had it about three times now.
And how to prevent such invasions to the greatest extent possible?
Thanks,
Susan
