I had the same issue happen then I got an adblocker and Ghostery for Google Chrome and I haven't had any issues since.
First Row has a ton of pop ups...but you should install a pop up blocker on chrome and you shouldnt have a problem... im using a free antivirus and ad blocker, and not having any problems...
