Recently when I get online, I have been getting a lot of these pop-up ads. I never get pop-up ads. I always have the pop-up blocker on the highest setting and it has never allowed pop ups but suddenly theyre coming up. The pop ups are all similar, same size, they take up my whole screen so I know it's coming from the same source. The ad that comes up usually depends on what site I'm on. If I'm on yahoo, an add will come up that's pretending to be yahoo. Or if I'm on a gaming site, a type of gaming ad will pop-up. In addition to pop-up blocker I have windows firewall on. And I recently downloaded Avast Home Edition and did a full system scan. The scan found a lot of viruses and took care of them all. But I am still getting theses pop-ups. I know this is not normal because I have had this laptop for years and never got theses pop-ups. How can I make them go away when I already have my pop-up blocker on its highest setting??
