SecureDNS won't go away

I’ve been having trouble with this. Whenever I go onto a site I’m pretty sure is safe, the secureDNS site keeps popping up, and I’m unable to disregard. It was getting quite annoying, so I uninstalled comodo, and it’s still showing up. Could anyone help?

Try these instructions i gave in another post

Hm, not working

Please see my post here.

In addition to CIS, are you using Dragon or IceDragon?
