Last night I turned in my MacBook Air, and when it was opened, a voice said, “Your MAC is infected with a virus. You need to take immediate action to prevent permanent damage to your system.” This isn’t verbatim, but it is what the message said. I have never, ever heard a message like that on my computer. It was a man’s voice. I decided to install the updated Catalina software and then after I rebooted, no more strange voice. Has anybody else experienced something like this? I have read through the forums and have seen people get pop-up messages, but this was an actual person’s voice giving me that virus message. (I do not own an Alexa-type device.) Needless to say, it was rather disturbing. Has anyone ever had this happen?
