I don't know exactly when this started, but every time I close IE window these days, there are always multiple popup windows(one regular is an ad about a hidden camera) behind it. At first I thought that they come up if I visit certain sites, but no matter where I go, they pop up. So I wonder if IE is responsible for that. Is it possible Microsoft changed IE maybe cecause they are tired of giving it free? Does anybody know how to avoid such popup ads?
