My friend with a Lumia 625 with WP8.1 w/ Denim recently started facing the issue of IE redirecting him to other pages. He said he was browsing through some pages when this happened. Is there a fix? Is this a virus?
And in IE push the 3 dots ... > settings > advanced settings > enable "Use Smartscreen Filter to help protect against unsafe websites"
and change your "cookies from website setting"
