anyway to stop the popup that directs you a page saying youve won an ipad?

Here's the link LINK

You get a pop up saying you've won an ipad and to click OK, there's no way around clicking OK and when you do, you are directed to the page I linked above.

This has happened many times in the past 24 hours and it did this a few weeks back IIRC.

If it is something on my end, pls advise and I will rectify ASAP.

I am using an HTC Thunderbolt (Android) via Verizon ISP.

Thank you kind sirs.

ETA: I did the basic stuff like reboot, clear cache, cookies, etc
