When I use my home pc,surfing the web, I see a quick flash of what appears to be a pop-up. It comes and goes so fast that I don't know what it is. I see it whether using IE or Chrome. It is always the same size and location. How do I determine exactly what it is? BTW MalwareBytes and Spybot S&D both say my system is clean.
Any suggestions?
