Safe Search doesn't know where I live!

Safe Search is truly annoying.

Why doesn't it know which country I live in? Why does it always prioritise USA website search results when I search, unless I put 'UK' in the search line? Chrome on its own was never a problem. I am about to uninstall Norton Toolbar unless this can be resolved. I have looked at every conceivable 'Settings' options, but none allow me to change my location.

Thanks
