How big is Sobig?

The SoBig virus is blasting through the internet about as quickly as the infection in 28 Days Later, but fortunately, the victims are machines, not people. Today’s Internet News story reports that AOL scanned 40.5 million email attachments yesterday, more than 4 times the more usual 11 MM attachments per day. Of the 40.5 mil, of those, 23.2 million were infected with Sobig-F.
