Try to figure out where the ad is coming from, most likely you have accidentally allowed a program to install on your computer. Go to the screen which allows you to check all the programs on your computer. Look down the list and see if there are programs which can relate to the ads you are seeing. My sister had a program which kept asking her to update drivers. I removed that program from the computer and no more ads popping up on the side of the screen.
