Let down

Google chrome has always worked well, but now I keep getting pop ups that say my "phone was randomly selected as lucky mobile device" Im pretty sure its a scam and I hoped Google chrome would have better security. Unfortunately I cant get out of the pop up without hitting ok which I wont do. Im probably going to end up deleting and redownloading...... If it happens again Ill be done with chrome.
