My phone forced me to download dfndr and I had to do research to figure out how to fully remove it. If you enjoy an app that metaphorically breaths down your neck and gives you daily reminders about all the other things you need to let it do to your phone that are unrelated to antivirus security then this is the perfect app for you! You will also be tricked into selecting their pop-up ads because of where they appear on your screen. I developed a special hatred for dfndr. I got AVG, it's good.
