    Awesome app!! Just downloaded it today on my new phone instead of my usual CM Security and holy cow! Pretty much the same kind of tools, but way cooler to use. And not as many ads popping up as CM. Egad, as of two weeks ago, they DOUBLED. And ad popped up every other window. Buh-bye CM, helloooo DFNDR! :* Full Review

    So far this is the best security app. I've used on my newest Android smartphone. My last 2 smartphone's got viruses, not sure how or why? I always used lookout and when Android first started that was a good app I thought but now I think it's been having issues for many years. To the developer's of this app keep up the great work! No offense to outlook but the times are changing and it's really sad that there are so many hater's "hacker's" that people have to be concerned when using there electronic devices these days. I think it's pretty sad.... Hopefully this security app and it's awesome developer's can keep our devices safe. Full Review

    Has given me no problems. I feel that this is the best app to have on your phone I already told my family and friends to use this app it really protects ur phone. Yes, it has ads but not as bad as those other apps and it has a anti theft to turn off phone from computer take a photo of the thief and wipe the phone of ur personal info and u can show the local police who has ur phone.

    How Bec Published date: August 9, 2017

    Everyday, disturbed by 4 to 6 messages, files need cleanup, apps need to close, CPU is overheating. I could not feel any overheat. Used another app to check my CPU temperature and it did not show any overheat. Each disturbance demanded my attention and showed ads. In Dfndr settings i shut off all notices. But then a Dfndr start screen took over my standard start menu. I had to swipe to remove the Dfndr screen before I could put in the security code to open my phone. Uninstalling cannot occur until you first shut Dfndr down in settings-security. Full Review

I had to Google how to delete this app followed the directions and it's still not off my phone. I am not the only one either..and they respond with the same dumb comment. Do not download this!

    There,s still the frustration with these pop up ads I don't want or need. I was content with my previous virus & cleaner app (pop up free), but thought this one might be better. I like the app, but OMG these pop ups must go. Overall it does its job. Full Review

    It slowed down my phone, and won't let me delete it. This app sucks big effin' time. STAY AWAY!! I am stuck with it but you don't have to be. Save yourself. Horrible effin' app. This app acts like it just got elected and I am now stuck with it for another four years. Suck it Defender, you suck a**. Full Review

    I would love to give 5 stars guys but I have only one complaint. The "cool down" seems to work but only for a while, then warns me again. This loop would go on and on but I've come to just ignore the warning when it says apps are heating up my phone. I hate to do that. Please fix or advise me and I'll gladly give 5 stars plus some. Thank you. I'm using a ZTE Blade X Max running Android 7.1.1 Full Review

    So far I'm impressed. Going to try to load it on a tablet that was refurbished when I exchanged a new one that was defective. It came with a browser hijacker embedded in a preloaded program. So far, nothing has gotten rid of it making it a worthless ivestment. Maybe this program will do the trick. Full Review

    This app has a ton of options and is easy to use. I'm not a huge fan of the number of notifications I get throughout the day, but that doesn't knock a star off the rating. Besides, I'm sure it's configurable and I just have been too lazy to take a look haha. Thanks! Full Review

    It's a great app to use. I love it!! It makes my phone run so much better. It helped me clean out junk I didn't even know I had in my phone still! It's a little such a very large app. There are a few things on there that I think are unnecessary but others may not feel that way. All in all, this app deserves its 5 stars. Full Review

    Once an App stuffs the Uber add up my nose more than once in an hour it suggests the app is no good. If I want a taxi I can get one like I can get an app that leaves me in peace without Uber adds every time I use the app. Have a nice day now. App deleted! Who wants ads morning afternoon and night?

    I absolutely love using this Antivirus App. DFNDR has saved me a lot of money by preventing viruses from invading my devices and destroying them. And simply because of this very app, it allowed me to save the money that I would've had to end up spending, that I really don't have to spare by having to go out and buy a brand new cell phone and a brand new tablet. I use this app everyday just about and I would 100% guarantee and recommend this app to anyone. In fact, I have recently told my Mom about it and she sounded like she was highly interested in downloading the app. She wants me to show her the app and how it works the next time I visit with her and my Daddy. DFNDR is so easy to use and navigate through that I really don't need to show her how to use it. It's pretty self-explanatory, all you need is a little common sense and with that being said, you'll quickly maneuver your way through. If I could rate this app with ten stars, there would be no hesitation, I'd automatically give DFNDR ANTIVIRUS, ten star's. Full Review

    This app is nothing but a data thief and spam. I hate it and if I knew how to find the app owners I'd make you pay for my device that you are now administrator over. Don't even download it unless you don't want control over your own device . Full Review

    This app sucks beyond belief. I downloaded this piece of junk and then shortly realized it didn't do anything and wanted to uninstall it. It will not let you uninstall and you are screwed with this app for the duration of your phone. Not even the store I got my phone could get it off and they said I was screwed. I strongly advise you not to download this worthless app because any company who makes an app that you cannot uninstall is worthless. Full Review

    I've had this app. now for a while and my opinion is it works well.. I deleted it & tryed a few others but I found that defender is the best app because it does everything from watching out for any hackers,virus even cleans and optimizes your phone.. This is the type of app I was looking.. 1 that does everything... I recommend it if that is what your looking for... Good job team...*****5 Stars Full Review
