Apparently you've picked up the virus that seems to be making its rounds. The same message ("I send you this file for your advice") appeared through the yahoo group with your name attached to it (first time I've recognized a sender's name).
I guess this is one that automatically sends itself to everyone in your address book and so it picked up the Yahoo ArtsEducators group.
If you have a virus scan program, make sure it's working correctly. If not, you need to get virus protection software to protect your computer.
I have no idea if this particular virus does anything other than send itself to people, but again it shows that it's not safe to open attachments even if it's from someone you know!
