Hello, I'm really hoping someone here might be able to help me resolve this issue I seem to be having with these annoying ad boxes that are constantly appearing in the bottom left corner of my screen. At one point, as I allowed the cursor to hover over this box, I noticed the word Criteo and looked into that, but even going into privacy, clearing my cookies and blocking Criteo from ever appearing again didn't help, so I'm no longer so sure it's Criteo, but perhaps a vehicle for it. I've tried Spyhunter, Malwarebytes, Ad-aware, Advanced System Care 7, and Spyware Doctor. I'm not really sure where to go from here. Any help anyone could provide would be greatly appreciated! Thanks, Rob
