My mom fell for a "your computer is running slowly" or some dumb thing a few weeks ago. I couldn't believe it. (she also has trouble with copy-paste so....). They had her install software that would allow them to take over remotely, but I don't think they got that far. She freaked out and sent the computer into Geek Squad and cancelled her credit cards. It was mildly hilarious.

Anyway, I may have gotten this call today. All my calls show up as unknown even if they are in my contacts. It's really irritating. But this lady was speaking in Chinese and I eeked out a couple of words that made it obvious I wasn't going to understand her, and she hung up.
