Having been bit by this warning message, all this sounds a bit too familiar.
At the time it was being caused by McAfee (yes, dust-off the anti-virus conspiracy theories) had flagged our domain as untrusted because our main virtual host (www.) was returning an HTTP 200 on a 404 Not found page. Yes, that's the "security risk" they found. sigh
