Hello, whenever I try to load a page, I get this screen about a free vpn has expired and to click the link to extend my free time. It literally will happen on about 50% of the pages I click. It could be gmail,youtube, even this website. It takes up the whole screen. Does anybody know how I can get rid of this? I have no idea how it happened? I did a smart scan with AVG and everything is good. Please help.
Is there a way to attach an image to this post so I can show you what it looks like?
