Bob and other CR members:
I got one also but deleted it immediately (without opening the attachment, of course).
Someone who has you in their email address book is infected and the clever virus simply "spoofed" your address in subsequent retransmissions from the infected PC to other folks in that same address book.
It isn't your fault and no one should ascribe it to you. Even if that individual only responded to an email to you once ages ago or added you to their address book w/o contacting you, you (and the others therein) are still fodder.
Classic bicycle content: This is in no way analogous to the potential for transmission of the dreaded ferrous oxide virus from any of my bicycles (including the infamous "Viking Patinator" from the 2001 Cirque) to yours due to parking too closely.
