The visual approach to virus propagation

I got this in my inbox this morning:

Some things that come immediately to mind:

Virus writers are becoming pretty good at avoiding filters. I use spamprobe, and have trained it to be merciless when dealing with messages like this one. It must have thought that this was an actual Microsoft email.
They are starting to prey on our fear. Given the recent slew of articles in the media about infectation, a virus designed to look like a patch against virii is probably very effective.
Branding is meaningless when dealing with rogues. Did you notice that the author(s) of this email didn’t just copy the Microsoft logo off their site? They reproduced it, somewhat successfully.
We are visual creatures, and our eyes react much faster than our brains. I consider myself a savvy internet user, and I had to look twice at this email to make sure it wasn’t the real deal. Intellectually, I know that Microsoft would probably never send out something like this, but visually it looked pretty authentic.
Some virus authors have a well-developed sense of humor. Can you just picture the sneer when s/he wrote that closing line?
My parents are screwed. They’ll probably be infected if they receive it.
