Recently there has been some complains regarding emails that has been sent out by the admin of this domain with attachments containing viruses. 
Just to clarify things, the mail server of this domain is not infected and has not been sending out unsolicited emails.

Two known virus that does this is the Sobig and Mimail virus.
