Just recently I am getting a grey rectangle with 2 concentric circles within the rectangle come up at the bottom right of any browser that I use, which is Internet Explorer and Google Chrome.
The rectangle with circles randomly come up and it seems that something is recording the sites I visit.
The circles appear dark and fade lighter so as to give the impression that it is recording.
It seems to appear when I go onto new sites and there is no set interval between when it appears. I have tried using Incognito window, but it still appears there too.
Any ideas what this is and how to remove..?

I have a screenshot but do not know how to show it here, can you please advise to help understand the issue..?

thanks in advance for helping
