I received the email displayed at the right. While Larry Grinnell is indeed a friend of mine who sends me email, the sender's email address was not his. This is one of several emails I've received, all extremely brief, and all with the exact same, format. The Subject line contains an exclamation. The body text contains my name and a single URL. I started saving them and experimenting with the URLs.
The first URL led to a place in Russia that displayed a weight-loss ad. I used a VM running Chrome to open it. When I used the same VM to open the more recent one (shown above) the VM crashed. I expected that. What I didn't expect was for it to take my whole desktop down, too.
