Whenver I use Chrome or Bing to search, I get RANDOM AND CONSTANT vdieo ad pop ups that play OVER any video I am trying to watch. I cannot make them stop!!! If I even get them to stop by pressing stop or pause, something else pops up or continues!! It is so maddening!! It makes any website unuseable becuase I cannot watch ANY video without these interruptions. I don't even seem to have Adobe Flash Player installed. It doesn't show up in my Program Files. HELP ME PLEASE!! I use Norton antivirus software and it is up to date. What do I do????
