Customer Reviews
  • Protects Device This is a very useful app. It has allowed me to free up space whilst protecting me from viruses and intruders
  • Best android AV This really does everything you want in a phone AV. The fact it patches OS vulnerabilities puts it leagues ahead of others (that ive used). Please dont make the mistake of bloating this app or altering it any fundamental way... too many great apps have gone down that path and its very hard for them to return. One issue i noticed definition updates need to be activated manually. Not sure how often it checks for updates, maybe im checking too often?
  • Bloody ads!!!!! Its a great app. Keeps phone clear of junk and what have they gone and done! Put ads on the unlock screen so you hit off them and load them whether you want them or not. Remove thesd ads and I'll give 5 stars otherwise I'm removing it. I would rather have a virus on phone than these stupid ads!!!!!
  • I love it so much Good App ever seen, kudos to you guys, you are doing great job, I give you five star ,love you so much
  • Multipurpose App Epic ! It checks internet speed, secures your phone, secures your apps and a lot more perfectly! Better than any other app lock too as its light on memory!
  • Love it 😀 So far so good my phone is much faster and Oooh so smooth ,glad I read the reviews my phone is now clean and safe
  • It found threats! I didn't even realise but there were privacy issues. So glad I got this app
  • Brilliant Had used quite a few other apps like this, but by far this is the one I'm keeping... Particular like the app lock...
  • Good but.....! It is good app .protect our phone from virus and app lock is good feature because we get 2in1 antivirus and applock but some times applock didn't open when right pass or pattern is entered.but after some time it will open and another is the this apps data can clear the security is Only for app so when data cleared security also gone.but antivirus is gooood.now I disabled the app lock .any way nice
  • From bad to worse What's up with all these ads?! They take up half of the screen, keep opening up and redirecting me to weird sites I have no intention of using. Everything was perfect until the last update. Newest low - app lock doesn't work anymore. I tried everything from reinstalling to turning off my phone but nothing. By the way - your ads still take half of the screen. Think I'm gonna have to find something else that works. I was so happy, but now it's just one big disappointment.
  • Seems to work Have felt comfortable so far Update the virus found a dangerous vulnerability awhile back. I would never have known it was in the phone. I have recommended to my family and business group to add this to their phones. I am very pleased with this app. Update still works as far as I can tell I have installed on 3 different smart phones.
  • CM Antivirus&Security From all the apps out there this one is by far the best android Antivirus & Security app I have used
  • Clean means no lag So glad I found CM and CM Security. My phone is as clean as a whistle and safe and secure.
  • Bloody irritating C'mon man! Such a brilliant interface but u hv completely ruined it with advertisements . It can't get more irritating than this ..I would request u guys to fix it asap coz m sure that like me there r more people getting pissed for the same reason as me .
  • Malware Security This app is very user friendly and it scans and protects my phone from all of the viruses that are all over the web. CM, you have a great app here and it's top notch stuff!
  • This app sick I can't Uninstall it and you hacked my Facebook ,Uninstall this off my phone
  • Imprescindible This app is a must. However in the last version they've included too much advertising (specially frustrating in the App lock).
  • Great App This app really "has your back" if you know what I mean!
  • Can you PLEASE tell me how to disable the stupid lockscreen it gives me. For a split second when I wake my phone you can see what I was on last and I'm quite sure the lock screen your app gives is the reason why. Thank you.
  • Virus free mobile Yes. CM Security is best. My friend suggest this. I hope my mobile will be virus free. :)
  • Applock screen ads What happened? It's a great app but the applock screen has lots of annoying ads since the last update
  • CM security Tracks you're device speeds up tablet, like new,all without troubling you
  • Absolutely 💘 the entire Clean Master family, but can you guys please make an application for laptop and computers!!!😘
  • Love it I can lock my apps so only I can get in them and it let's me know if a website can harm my phone
  • It says it makes your battery last up for 11 days without charging which i think is not true i had the app before & didnt do anything with the battery so till it actually does what it says i only give it 3 stars
  • Good App CM private browser should have a shortcut key
  • Its really good Good this ups....but may phone tab3 why very slow?I dont now what happen this...:( its soo bad
  • Gills all the virus Recommend to people who got alot of virus and hope this will help them bye
  • Please increase the photo vault limit Increase the photo vault limit please its like 50 images i want unlimited images like before i am using s6 edge plus
  • Awsome Best one out and for free makes it even better and it's better and updated more than paid apps good job guys and ty
  • It works well without telling you a thousand things that are wrong with your device. I like it a lot
  • CM SECURITY Good thing to have on your phone. It helps with many problems that can happen and you don't even know what is happening to your.phone.
  • Not cool Guys its not cool to force someone to download ur up even though they dont want it :( ur ads keep on popping on kat site.
  • Annoyabale apps. It makes my android gadget not fully charge when I charge... I though it helps my gadget to protect avoiding in battery heats from the other apps but I really disappointed that your CM app is the trouble maker from causing high temperature for my battery. So that, gaving back your application by unstalling it. But its so hard to unbind and so slow. Just like Peter Parker's prof from Spider-man 3 saying: "It needs to bind the host to survive, but its hard to unbind".
  • It's been good till the new update...the charging screen saver has become annoying with those app ads.
  • love it awesome app Awesome app I love it it takes the persons photo when they got your password wrong three times and you don't know them or you don't want them in your device and you will have a password on all your apps great app you will love it...................
  • Very fast and powerful My phone gone crazy and memory was always full untill i got the app. It was fast and very very powerful
  • Can catch snoopers readhanded..pretty gud antivirus. Speeding the phone to a little bit. Nyc
  • Reducing from five to three to two stars for ads Latest one has ads. The app is good but it's combining lots of apps together into one. Caller I'd doesn't work. All calls are shown up as Canada so reducing the star for that. I only want app lock feature so I cannot use it as it is merged with other features. Create separate app for security/antivirus, another for applock, another for phone boost, etc and then decide the permissions for each app. O am not granting you all permissions.. Privacy concerns here..
  • Good/Bad....can't say. Some features of this app is working but the feature which I need and i.e "app lock" is not working in my Sony Xperia M4 aqua so this app didn't worked for me.
  • Too many adverts I used love this App. Was going to give it a 5* rating until the recent update starting having adverts i dont care about. Get Rid of the adverts and i'll give it a 5*
  • Phanindra Nath Nagumalli The app is too good, i like it very much, but the app is take 48 mb space on my mobile, i think developers need to be reduced it.
  • THIS THING DOES WORK After my tablet had a thing were it said do something and win a I phone 6 for free I started to get verses but when i install this it work I have no more vireses. :)
  • I love this app but I do have one issue with it. It won't let me activate the find phone option. I had it before and now it doesn't work
  • So far, the app makes the phone works fine.... but not 5 for the adds, I wish I can control the icons in my home screen
  • Awesome If you wanna get the most security out of your phone download it. Also download CM Locker for 100% protection.
  • Awesome Before when I was grade 4 my phone was lag as virus but now beacause this app come my phone is finally not lag thank you for not making this app I will give 5 stars keep up the hard work :)
  • Not bad Im still new on here but so far so good. I like the Ability to see who tried unlocking your phone. Its also cool somebody can be on ur phone but still can use your apps if they are locked. Everybody needs security.
  • Fustrated Was great.now yoy keep telling me I have 2 viruses I go into fix and nothing happens it doesnt show you've removed viris. Please fix as I do not use my phone for entertainment anymore because im freaked from you telling over and over I have 2 virus. Please fix now. I cant loose my phone to viruses
  • Cm security Scans and protects your phone. Keeps all off your apps private. Keeps your phone from allowing anyone to see your private stuff.
  • Geat antivirus app Great application for my androids: before samsung galaxy S III and now LG 4G
  • Awesome Caught my sister tying to unlock my phone after 2 times it took a pic of her lol
  • I love it Now i feel like my phone is safe and i dont have to worry of others looking into my personal data
  • Love CM Security, love how you can pick and choose what you want protected and how it snaps the persons photo trying to snoop. Great work CM Security.....
  • i think its pretty good it alarms u whenever something is wrong and can do mostly anything like locks n photos n clean outs 👍
  • Superb app ye aap ko maine 10 no 10 diya hai. Samsung grand max ke liye mast hai. Thanx admin for providing app
  • Great app better Norton Better than paid version of Norton and Mcafee did on alerts. Great app worth it for sure
  • Love it I highly recommend this app. This app helped save my phone from crashing when I knew nothing about it
  • A Bunch of Ads!!!!! A bunch of new ads now showing up everywhere with this last update. I thought this was security software not software that secretly adds a bunch ads that you did not ask for!!!!! Removing the scrap now!!!
  • Best Virus Protection Ever. Well, the title speaks for itself. It's by far the best protection anyone can get. The best part is that it's free!
  • Worst Update When I try to open my apps and try to put my password (from app lock system of cm security) it just limitless slow & even if I put a wrong password and try delete and again try to put it just damn so slow, fix it or uninstalling this time wasting app.
  • Amazing!!! You get warned 'bout viruses n keep ur device going cool......
  • BEFORE I LOVED IT, ITS TAKING SCREENSHOT SIMPLY,PLEASE SOLVE IT BECAUSE I M BIGGEST FAN OF CM SECURITY
  • Amazing app lock.... This application is cool... 😎 it takes the pic of the one who is trying to snoop into our private applications.... I LOVE & LIKE THIS APP....😘
  • It seems good to me, but snapshot can't access my cam. Need yuor help
  • Very good The password should have other lock options, like numbers and letters too. Please add mobile data lock, too.
  • I found a small problem with it. When you hit the tab button it shows the main screen of the page you try to enter. But that aside it a pretty good app.
  • A great app to have. Saved my phone so that I don't have to buy another one so soon.
  • Since after I update my private messages option don't work any more. All message keep showing in the status bar plz fix
  • Amazing It instantly stopped viruses and protected my phone
  • Best app ever This app is the best it even lets me delete space that I don't need cuz my phone is messed up it doesn't delete all the space that is supposed to and that helps me delete that and also locked my apps for me so no one can get in and I can't stand for problems I can even on happens in one app
  • my private galary thanks this apps kase ndi nabubuksan ang important Kong tinatago sa galarry ko.
  • Awsome app It's awesome I just got it and I had 3 threats on my phone and some junk files that took up about 25.63 MB and it just cleaned all of it right their on the spot just by the click of a button
  • So far it's working fine with my sony Xperia phone.. Just now I downloaded it
  • Its OK so far Hey so I have just tried this out but I think there's something suspicious... 😞 for example hacking my phone..
  • Can someone tell me how you can prevent cm from being uninstalled as I've been through settings and cannot find this feature so makes app useless. Plus suddenly started to get advertisements every time I try to unlock screen. This can happen upto 3 times plus before I can get into an app. EXTREMELY time consuming and annoying. If it carries on I will certainly be uninstalling.
  • Its Petty Good I like it but I am annoyed about Installing extra appd like the Trojan scanner and other apps which are all related to antivirus. If you could put em all together into one app it would be the best thing ever.
  • It was cool before ads showed on App Lock screen. An awesome app I'd say for the AppLock. But what do you do if you forgot the password while you have locked the mobile data and WiFi? And it was cool when the AppLock screen did not show ads on the locking screen.
  • Now my phone is tooo faster, thank you so much cm team
  • Awesome Thats nice!!! Cause I am free to scan my apps like I know now that my clash of clans are full of viruses
  • Its ok U should put it to where u can put da app password as a password so dat it would be even harder to guess someones password then i will rate u 5 stars
  • Royally awesome app! Where have you been all my life?
  • Loved CM Nice. Safe ur costly mobile
  • Hurray! Auto WiFi on & off feature is back Auto wifi on & off is one of the greatest feature of this app. This feature is very very much helpful to me. In fact this feature made me to forget the wifi switch. My wifi automatically get switched on whenever my phone is in wifi range and switch off when its outside of it. Love you CM
  • Very good Antivirus for smart phone I am using this app last six months. It is protected my phone for virus and others issues. Great app and great protection. Dounload this app and enjoy your Internet and files.
  • Love it I was having issues with my phone crashing at random intervals and strange files appearing on my device so I downloaded malware bytes which did nothing so I then got this beauty and everything changed. It caught a Nasty Trojan that 95% of androids are vulnerable to through messaging.
  • This app is the best We all need to be able to have a secure phone. This app takes the worry out of it. Still loving this app. Glad that security is number with CM.
  • Excellent This is a awesome program downloaded 5 test viruses in a row and caught every one of them fast did real good thx cheetah mobile.i discover this program under NYSE cmcm
  • Please .... enough with the ads I really liked this app until I got the latest update with ads on the applock ..... Come on guys. .. enough already .... !! Can I pay to get rid of the ads or do I start looking for something else?
  • Ok, but idk Its an awesome app... cant say anything bad, but with the charging protection screen, awsome idea, but laggs and slows down my device! Oftens freezes it for a while, is there a fix for this in the works?
  • Great! Its so easy and so secure apps.that i've ever known for todays generation.It only use a small space on a system just not like the other antivirus that i've been used before.I hardly rate 5 star in almost apps that i've been download before.But this time i would.Thanks for this great apps.
  • Go Back to the Drawing Board This Update did not update the app. Instead it requires me to change my phone's accessibility settings - AND THAT'S ALL IT DOES! Not going to do it. This is not an app UPDATE, CM "Security." Try again.
  • New goodies seam ok so far eggsalad lol Very well done...however an auto cooldown and/or boost would save heaps. Tyvm Richard
  • It's good but the app lock has stopped working to prevent my apps locked from being moved from my sd card . Fix and I will give 5 star's
  • 0 rating for Ads in Screens Last time ads in cm locker and this update ads in app locker. Very worst. I don't need your app. I ll remove it..
  • it's awesome....! I Lov it, but can you please ad sms blocking for us? we really need it, or else we have to find an application with the two in one.......
  • New user This security app is the best one I have ever tried. I will install this app on all my android devices.
  • Loveit the app s cm cm. Com love USA Bige BOOSe of seicorty app.s all made of usA Tecnolage is made for hever long Time fraind
  • That's not what I meant... The app is running fine, but I wanted you guys to add an option to lock uninstalling apps without a password/pattern. (LG G2 D800)
  • CM Security Antivirus Applock I like it...Had a few issues with heuristic engine being over sensitive (asking me to uninstall apps I use regularly like news apps etc) but it hasn't happened in a while now which is very good. Overall it's the best out there - five stars... Edit - love the new integration with Google Chrome History being cleared with a click of a button. If i could give this app six stars i would because it works beautifully with my Z Ultra LTE lollipop
