Diagnosed the problem as originating with Kaspersky Internet Security. I had some weird issues with some sites when I 1st switched to kaspersky but sorted them out by disabling the virtual keyboard and dangerous wensite blocker etc. and had disabled all the browser plugins a while back and had no more issues.
The one I observed and posted a pic of I have never ever seen before. Clicking the advanced tab gave no useless suggestions of what may possibly have happened but as this was google.co.uk I find that hard to believe.
