I have received a message from Rick F's friend using Prodigy.net, the message was also addressed to Rick at his Bellsouth address.
We will have to await input from Rick to know if it provoked a warning when it was received by him.
As I have mentioned, I am a user of Comcast so this message was received by me on a different ISP, otherwise the message is identical for both of us.
However the message sent is sufficiently similar to the message (whose contents were posted here) yesterday to confirm the conclusion reached by
Vlk.
Here is the relevant part of the message we saw, as delivered by Bellsouth yesterday (with Vlk's comment in red):

Hi Rick,
Glad to help out. Viruses are a big problem for all of us.

Here is the relevant part of the similar message as delivered today by Comcast to me:

Alan & Rick,
Here is the test message you asked for.
I hope it provides information that may be helpful to this virus alert problem.

The thing to notice is the three lines colored blue (by me) in the Bellsouth delivered message above. These lines are being added by the spam filtering component of the Bellsouth mail system. As Vlk commented they have obliterated the blank line that
must precede the message boundary line (starting --) that denotes the start of a new section of the message. You will also note that avast can properly place the X-Antivirus headers in the message as received on Comcast because the message has not been damaged by the Comcast mail service.
