No WINE installed. Guess it piggybacked in on something else. Since I'm not running Windoze, I should be safe. That's one of the better reasons for running Linux in the first place. Thanks.

That's a Windows Trojan.

Do you have installed WINE on your Linux partition?
If not the exe file cannot be executed. Perhaps a Java applet on a website you visited saved it but couldn't execute it.

What at about the possibility that Comodo is "salting the mine"?

If akonadi indexed some malware code, it would also be present in the message itself and seen by the scanner, right?

Yup.
