Strange Comodo secure dns behaviour!

Hello!

If I try load this web page with my browser (CD v9) I see an error message of comodo secure dns!
web page:
a20 -
www.a20.org

error message: see the jpg file.

But, it’s strange! I DON’T USE comodo dns servers! I checked the settings, and I use another dns, not the comodo.
How can send me an error message the secure dns server?

Thanks!

Can you post a screenshot of your DNS settings?
