I saw that one Saturday when I was using my Android phone.When I was on my android phone yesterday, the only one I got was the one saying I was infected with a virus (ewww) and needed to download the app to get rid of it. It was a very good imitation of the page you get from an actual anti-virus program.
Still nothing on iPad, but I just tried my phone and it happens on almost every single page load. It's obnoxious.
Anyone tried the mobile skin? I know it sucks, but maybe it would make the site useable.
Apparently Apple added something that allows the popups and now advertisers are taking advantage.
