Also CNN supposedly have a story about it on their show.

No mention of it on their Website:

http://www.cnn.com/

Have a browse NO MENTION AT ALL!

But the Warning E-Mail Contains an attachment which is unusual in an E-Mail form the AFP Warning about Attachments.

The E-Mail originally cane from: krworley@bigpond.com

Usually the AVG free edition anti virus works dont works in infected archives...
Good free anti virus programs would be anti-vir, clam-win and avg. I personaly like avg or anti-vir.
i think avast works better than AVG
I recommend NOD32 Antivirus System. This is really a good one.
