Virus notification question

[marcos maniac]

I keep getting the following warnings from yahoo

Yahoo said:

"Yahoo! Mail Virus Protection detected the virus '"W32.Netsky.C@mm"' in the file '"freaky.zip"', attached to the enclosed email message. We scanned the file using Norton AntiVirus but were unable to clean it. Therefore, we removed the content of the attachment from the message. Please contact the message sender if you want to receive the attachment. They must clean the file and resend it before we can deliver it to you safely.

How do I find out who has sent the mail?????
Had the above message/e-mail several times now.

I don't think you can - they spoof the address. An IT expert might be able to figure it out but I can't. I've had dozens of similar cases - basically someone infected is online and you're in their address book. You can leave things as they are, or if the subject line is always the same, use Message Rules to delete them from the server so they don't bother you.

All you can really do is just keep your AV bang up to date and let it blow over, IMHO.
