xpaj-gen infection?

[Mike Kerner]

i decided to try out avast for mac, and almost immediately i got a message
that one of our compiled LC windoze apps is infected with xpaj-gen.  I
don't see this topic mentioned anywhere.  Sophos didn't ever see anything,
and neither did Norton.  So maybe it's a false positive, and maybe it's
something else that everyone but I know about.

   and did a little diving.
And God said, "This is good."
