Are you sure the messages are coming through your MailScanner gateway?  I
had a similar problem a year or so ago where Trend would pick up viruses on
Exchange.  Turned out that one of my users had pointed their Outlook client
at their home ISP so they could check non-local mail account.  The viruses
waltzed right in with nary so much as a 'howdy-do'.  Fortunately, the
bouncers from Trend took them in the back alley and pummelled them before
they could cause a ruckus...
