I think it is a good read : http://www.vnunet.com/News/1137161
Interesting.AV vendors are unaware of the latest virus until they are contacted by a cheated, disgruntled customer who has fallen foul of this email pest.
This customer is the nominated sacrificial lamb, the accepted loss. He is obliged to send the offending virus to his AV vendor for analysis and the development of a signature for the benefit of more fortunate customers.
It is then down to diligent IT staff to download the signature and update their software in order to stave off the latest viral threat from their technical assets.
So one customer's IT network will lie in tatters for the greater good of the customer base.
