Well, I just got a call from what I assume is the same Indian fellow. I asked him what OS I was using and he was baffled. Then I asked him if he had installed the TeamViewer software on his personal computer, to which he had no answer then replied he did not have a computer. I then told him I went to the TeamViewer website, when I actually had not, and he asked me to allow access for him. No chance. At that point, I asked him why he was calling a Mac user to update Windows software, at which point the call was disconnected. Anyway, thought I'd add my experience with this scammer. Too bad people can't get jobs where they add something to society. Unless their bosses are telling them they are adding to the good of society. Don't know. Anyway, I spent 7 minutes of his time.
