Since installing COMODO Premium (on Win7), sometimes when I search Google through Chrome’s url/search box, the search is automatically re-directed to a Comodo Search page.
You just have the Comodo DNS installed. This site is not working so it will redirect you to your ‘original’ DNS. That’s all. Comodo DNS was “optional” in the CIS setup/install.
To be exact, I now seem to remember I actually changed the DNS address manually myself, following recommendation and instructions during the COMODO setup process.
