Pop Up Ads All Over
I have just, in the past couple of days, developed a pretty serious issue with pop-up ads appearing all over the place on my phone. They come in two different ways. 1st is when an ad pops up over the top of another app. This has happened with GO SMS and with the Facebook app for sure. I can't recall what other apps it has happened with, but I don't get the impression that the ad is related to the app I'm in. I've had them pop up on the home screen as well.
Here is an example of a pop-up ad when I opened GO SMS:
I also have it happen where I open my browser (I use Chrome) and it will automatically launch a new tab, then the tab will act as a redirect and send me to the Play Store for another app (basically sending me to the download/install page for an app).
I don't recall installing any apps just before this started happening. I believe that my app list is the same before and after this issue, but I'll keep looking. I have not rooted and am using the Nova Pro launcher, if that helps at all.
How can I figure out what is causing this and, most importantly, how do I make it go away? A factory reset is an option, but I'd like to keep that as a last resort if possible.
Thank you for any and all help.
