Malware appears to have hijacked my browsers when I click on links within the windows. Your help would be appreciated. On opening browsers they open normally then when links are clicked, pop-unders load and take over the tab and open new tabs. Warning pop-ups display on the screen and they also open new tabs with more advertisements & other ad websites. It is very hard to stay on any one given screen as once the pop-unders open, they disable the page. A new page has to be opened and the links clicked quickly in order to click the links.
