Well, there is a big lack of information in your message. You don't know the virus name, you don't even know if there was a virus at all...
Do you still have the message from your friend? How your friend discovered that his computer is infected? How does he know that the message to you was infected?
Many modern viruses fake the sender's address so that it looks that the message was sent by somebody different than the really infected person. Maybe you and your fried are not infected at all? We are not able to say this without some additional info.
