Weird Blue Boxes

Hi Guys,

I am having a problem with a new site displaying properly in IE 11.

We have built a site using WordPress called http://www.acar4all.co.uk.

The site works and displays well on every machine and browser we have in house plus on friends and colleagues machines.
However when displaying on the clients Windows 10 machine using IE 11 blue boxes appear as if something has been highlighted.

The puzzling part!

We cannot replicate the same issue on other similar websites on the same machine.
When we view the site using IE 11 on our machines it works fine.

I have added a couple of images showing the blue boxes and can email these to anyone wanting to see them

We tried the old compatibility view fix, it got rid of the blue boxes but did not display elements on the page properly.

Anyone????
