This is odd, it's just on the new tab, or if you open up another copy of chrome after the first is running.
I don't know why none of the tools have picked up what's causing the redirect.

Ok well seeing as system restore didn't help either, I zapped google, reinstalled it, and re set everything up again, that seemed to do the trick.
I *think* it was a Kodi install that did it, but I'm surprised that Chrome itself doesn't have it's own anti hijacking measures.
