I don't think so. I won't go on record with what I know but I do know that Microsoft has consented to allow governments audit, review, and sometimes even modify their source code.

I suspect a polite request (perhaps backed by a threat including the L-word) will get them far further than a virus.

Edit: Others have pointed to public documentation of this program. I believe the two cases I was aware of at the time were the governments of China and Germany.
