My ad blocker (Adblock Plus) stops them on my computer, but I've been having ongoing problems with pop-ups on my phone, especially one that says I've won an Amazon gift card (spam) and one that tries to tell me that my phone has a virus (it's also spam - my phone is clean). Both ads are persistent and difficult to close without clicking them. I posted about it in this section of the board a few weeks ago, but didn't get a response. In the meantime, I've stopped using my phone to access the QB because I can't risk getting a virus or malware on it.
