Why is AVG AntiTrack interfering with appearance of Google, Google Searches and Google Images?

Hi Dyfed.
We regret the inconvenience caused to you. 
I have escalated this to our senior technicians for a resolution.
We'll get back to you once we hear from them. Appreciate your patience meanwhile. 
Hello Dyfed,

We appreciate your patience.
Since there is a version released recently for Firefox browser, we request you to update it and check whether the issue persists with AVG Anti-Track enabled.
We would also like to know whether there is an issue with other browsers like Edge and Chrome?
