About 10 days ago I started to get pop-ups on my phone. The are rectangular boxes that say adchoices. The ads change all the time. These pop-ups are on any main screen on my Samsung Galaxy S5 phone and any application I open. Places where it pops up: Home screens, texting, emailing, chrome browser, IE browser, any game, music apps, camera. It pops up all the time. I've uploaded a screen shot. See the rectangle that says GET COUPONS. That whole bar will stay there while I switch pages. If I click on my text app, the rectangle will move to the bottom of the screen and cover the keyboard. I can get rid of it by clicking on the X in the upper right corner two or three times, but this pops up with just about everything I do. The apps you see on the screen shot have been on my phone for a very long time and I have never gotten these popups till about two weeks ago. I have only downloaded one program in the last couple weeks - Sworkit. I immediately deleted this program, cleared my caches and restarted my phone. Still popups. I went through and deleted any extra programs that I have not used in a while. Deleted ALL cache, restarted. I used avast and malwarebytes but they say everything is clear. I do have a lot of apps on my phone most of which have regular updates - maybe its is one of those? I am not sure what else to do other then factory reset. Does anyone have any suggestions?
