When I went to bed last night, everything was hunky-dorey with my computer. But I woke up this morning, and I noticed a new icon in my dock. (Attached.) I don't THINK it was there when I went to bed, but it could be I hadn't noticed. I am a tad suspicious about a message that popped up while I was on Amazon which said I needed to update Adobe. I didn't give it a second thought because it was Amazon's site, and that's not the way they generally rip people off. It identifies itself only as "Booking." I can't tell the actual name of this thing, which only intensifies my desire to track it down and kill it. I've searched and searched, but I can't find anything on my Mac called "Booking," "Booked," "Book," or "Book.app" I ran Malwarebytes, and they found one suspicious thing, but not whatever controls this Booking thing. I'm totally out of ideas. Again. Is this ringing any bells with anyone?
