Whenever I go to a website, the graphics and pictures are normal, then there is a gray background and there are no graphics. I feel like it's something that I "picked up" visiting a shopping site or something, but I don't know how to get rid of it except to click on a little tiny icon that pops up in my tool bar or next to my tool bar whenever the gray screen shows up. It's driving me nuts! Please advise if anyone is more tech savvy than me....(which most people are, I'm sure)
