Roberta and Brian, it sounds like your Browser has been “hacked” so to speak on your end on your device. See this thread here: http://www.scrollsawvillage.com/forums/topic/28592-hacked/
you probably need to delete your browser histories, remove cookies, and remove web site data to cleanup your device and get it back to working properly. I have had it happen and it is frustrating I know. Hopefully clearing out your history and. Okie s can resolve it for you. Roberta, that thread has a link to an Apple support document that that will give specifics on how to do for your iPad. Brian, not sure if your phone is Apple or not. If so, it would be pretty much same.
they haven’t hacked your device per say, but have hacked your browser and is using redirecting software or something that latches on to your visit history here to give you those pop ups.
