For about the last week Chrome has been trying to open tabs not requested by me. They are the same tabs over and over. They are as follows:

This behavior happens about twice a day. Fortunately the Malwarebytes extension is blocking these attempted downloads. I am at a loss to find the cause of this behavior. The AV I use is McAfee and I have run various scans such as Malwarebytes, Adwcleaner, ESET OnlineScan and even Norton Power Eraser which have found nothing. I was wondering what was the best way to identify and remove the process trying to launch these pages?
As a temporary fix I am thinking of simply blocking the offending domains in Chrome although I occasionally use some of them in which case I would switch to another browser. I have not experienced any problems with my computer (Win 10 Pro) or other browsers such as IE or Firefox.
