Chrome new tab with non-empty URL

Hello,

when activating the Norton Security Chrome extension, new tabs in Chrome (MacOS and Windows) always contain "https://www.google.com/_/chrome/newtab?espv=2&ie=UTF-8" (which redirects to "https://www.google.de/webhp?ie=UTF-8&rct=j&gws_rd=cr&ei=...") instead of being empty.

This behavior is very annoying, because I have to wait for this redirect to happen, before I can enter a new URL.

Is there an option to change that behavior?
