What Is the Best Antivirus App for Android?

Dan Price 27-04-2015

Smartphone antivirus software has become big business in recent years. The Android operating system is under an ever-increasing threat from malware, viruses, and other undesirable programs, and the requirement to protect yourself against these threats Smartphone Viruses Are Real: How To Stay Protected Read More is now more important than ever.


With so many antivirus apps available and the selection growing on a daily basis, it can be difficult to determine the quality releases from the ineffective ones. In this article, we take a look at some of the best antivirus apps in the Play Store to help you make an informed choice about your coverage.


It seems that almost any list about antivirus software is obliged to include Avast, and it would be extremely remiss of us to leave it out.

Launched out of Prague in the Czech Republic in 1991, Avast now controls 21.4 percent of the worldwide security vendor market and boasts 233 million active users. It started life as a Windows program but now also has releases available for Mac, Linux, and Android.

As with their desktop versions, the developers of the app operate a freemium model. Nonetheless, the free version should be more than enough for most users. It includes “live” scanning of installed apps, the ability to schedule phone memory and memory card scans, SMS and call blocking, web shields to protect you against spyware and malware-infected links, and the ability to pin-protect up to two apps. If you have a rooted device, you can also manage firewalls. The paid version ($2 per month, $12 per year) adds unlimited pin-protection of apps, ad detectors, remote data recovery, and geo-fencing.

In terms of threat detection performance, independent security lab AV-TEST said the app detected 100 percent of their 2,950 malware samples in their January 2015 test, beating the industry average of 99.3 percent.


Kaspersky Internet Security

Kaspersky is one of the most well-known and widely trusted names in the antivirus sector. The company was founded in Moscow in 1997, and has gone on to have 300 million users with offerings across all the major platforms Check Your PC Fast & Free With Kaspersky Virus Removal Tool Sometimes, even when you run professional antivirus software and anti-malware apps, your computer may still start acting a bit screwy - leading you to wonder whether it's possible some new virus somehow made it past... Read More . They made the jump from desktop to Android in 2012 and now provide a solid app that strongly competes with the other mobile-based market leaders.

Their latest Android release finally did away with separate versions from phones and tablets, and is much more streamlined as a result. Like Avast, they operate a freemium model. The free version includes protection against viruses, spyware, and trojans, an antivirus scanner, and anti-theft protection. The $14.95 per year premium version adds real-time protection, cloud protection, SMS anti-phishing protection, and privacy protection.

Drawbacks include the necessity to create a Kaspersky account before you can even open the app and the lack of a white-list.

The January 2015 AV-TEST analysis gave it a 99.9 percent threat detection rate, down from 100 percent in November 2014.



AVG has been downloaded 100 million times from the Google Play Store and has an average rating of 4.4 from 3.3 million reviews — facts that mean you can be sure you’re going to be protected by using a well-regarded piece of software.

Unlike some of its competitors, the free version comes well-stocked with features, including identification of unsecure device settings, a task killer to identify apps and processes that are eating up your device’s RAM, a full anti-theft suite, and phishing protection. The pro version adds social media protection Are Your Social Friends Infecting You With Malware?

Despite its popularity and impressive range of features, AVG performed below the industry standard in AV-TEST’s January 2015 analysis, with a detection rate of 98.7 percent (0.6 percent below average). The institute also noted that it identified four false positives, something neither of the previous two apps did.

Finally, be aware that they offer separate apps for phone and tablets.



Lookout is probably the slickest antivirus app in terms of design and ease of use, and has garnered a huge following as result.

Like most offerings, there is a free and a paid version. The free version comes packaged with anti-malware protection, data backup, a remote locator (which will work even when your battery is dead), and a remotely triggered alarm. The paid version adds a full anti-theft suite, a privacy advisor, and remote data deletion.

The app detected 99.4 percent of 1,460 malware samples in AV-TEST’s independent analysis which is about on-par with the industry average.

Bitdefender Mobile Security and Antivirus

Bitdefender is different from our other four suggestions in that it only offers a paid version. The initial download will give you a 14-day free trial, but thereafter it will cost you $1.49 per month or $14.95 per year.


The money is well spent. Aside from a 100 percent detection score with AV-TEST, they are also at the forefront of innovation; they are one of the only antivirus apps that will already seamlessly sync with Android-based smartwatches, they offer a “Phone Alert” that will alert you when you step too far from your phone to prevent you from leaving it behind, and they use independent testers as part of their development process.

The only drawback we came across was the lack of scheduled scans, meaning you can’t set it to run in the middle of the night when you won’t notice.

Do You Even Need It?

A lot of commentators and analysts are convinced that Android antivirus apps are unnecessary. The modern Android operating system includes vast amounts of stock security, meaning these could apps could all be redundant. The truth is that if you only use the Play Store and install “standard” apps, you are probably safe. Nonetheless, adding third-party peace of mind is certainly a sensible approach, especially if you have a rooted device 6 Key Tips To Avoid Bricking Your Rooted Android Device When you own a rooted Android phone running a custom ROM, you need to take some precautions or risk "bricking" (destroying) your device.

    I am using ESET for more than a year. Really great antivirus for mobile and PC.

      An update is necessary to a statement made above. There IS a free version of Bitdefender on the Play Store. It is called Bitdefender Antivirus Free. It is a tiny app that uses the same detection engine as the full suite. It has zero impact on resources, yet still provides fast real time scans of apps and storage. No lock, wipe, puke etc., no nosing around in your underwear drawer, no call management, just an awesome antivirus app. These other apps are trying to remain relevant with gimmicks, i.e. - "we can scan apps on the Play Store before you download them, etc. Soon, it will be "download our app and get an e coupon for a McDonald's cheeseburger. By the way, read these scary push notifications about how MALWARE is coming to get you, and our app is the only one that can keep you and your family safe!" M.F. PLEASE! MY Advice is use your head, check it out before you download it, oh, and if you STILL don't feel safe without giving someone else control of YOUR phone, Google will wipe, lock, protect you for free without a poorly made app using up your RAM, and accessing your contacts, and trying to sell you shit. This is common sense signing out.

    Yeah Dan, like so many others have already said, CM security beats every app this article mentions hands down. Check out a/v comparatives for its real world results. And for all those using clean sweeper and similar optimization apps, all you're doing is killing your battery and making android work twice as hard. I know we've all been trained to clear temp files and keep things from running in the background from so many years of Windows use, but the android os doesn't work that way. It needs those apps stored in your phones memory to achieve optimal performance. I too was using clean sweeper and task managers, until I realized how much more juice I had at the end of the day by not constantly purging everything. I still use CMs data cleaner after a week or so, but that's about it. Oh and cheetah mobile also makes the best backup app available. Migration to a new phone will never be a pita with that app. It backs up everything except your media. And gives you 10gb for life.

    Nice and interesting article. I am an avid follower of makeuseof. I have it on my smartphone.

    I had CM Security, Clean Master and the Battery Saver App. until one day I realized it couldn't be saving battery or anything else because every time I pulled my phone out I was following instructions, procedures and prompts. The CM apps were getting more phone time with me than my BFFs or the hottie I met at the club the weekend before. It was like having a wife and kids in my pocket that needed my attention constantly. Now that I uninstalled all of that crap I feel like a free man again, Ahhh!!!

    None of Antivirus applications has capable to alert the user before the harm invading the device. All of the only alert after the down loads of applications and etc. No benefit through keeping Antivirus expect this provides a false feel that their device has been protected.

    Another vote for CM Security. It even has a lock screen app and some kind of battery saving wallpaper app that I haven"t tried yet. Yes, the ads are intrusive. That's the cost of a killer set of apps being free. When the ads show up hit the home button. It's not rocket science. *shrug* My only real complain is it's not yet a suite like Eset or Kaspersky.

    None. If you use some common sense and download apps from the Play store you're safe. Even if you do side-load a lot of apps make sure you verify where it's coming from and if it's a trustworthy source. In other words don't download and install apps from some shady site you found in a Google search.

    360 Security, because not only does it check in real-time, it also removes left over stuff during (incomplete or sloppy) deinstallation, lets you clean your phone (caches, thumbnails...), boost memory and battery life.

    In that it is similar to Clean Master but much less intrusive with respect to in-app ads.

    • Dan Price
      April 28, 2015 at 8:54 pm

      Yeah, that's the worst thing about Clean Master. They annoyed me too much, I deleted it...

    • Kris
      April 29, 2015 at 2:19 am

      Dan and Chris,

      360 is really decent. I don't run it full time, but if I'm going to be doing anything... questionable, I'll run it before, during and after then uninstall again.

      Clean Master, though... OUCH so much annoyance!

    I used an AV once on my Nexus 7 (2012), then I rooted and flash 3rd part roms. Never reinstalled an AV since, never had a problem either. I do occasionally sideload apps, nothing that I don't know about, or have researched thoroughly. So I am cautious about what I install.

    One word: Esset. I've used at least 2 of the antivirus reviewed/ recommended above but none compares to Esset. It works silently in the background, doesn't nag or bother you in anyway unless threat is detected...and real threats too, not false positives or whatever you call it.

      I agree with Keith. CM is very small but mighty. They offer all their apps for free, & I love free. They give you private safe browsing, have Clean Master which cleans up junk (cache mostly), & of course scan & other grest features. They get some complaints because they offer quite a few smaller apps instead of them all being packaged together. However, you can install the Struts or Heartbleed scanners, scan your phone, & then uninstall both when done. I love Free!!
      I also have Trust Go but find it's a CPU hog, & battery hog. But I use it for a loved ones phone security. I use Avast too . Maybe it's overkill but these keep my phone safe.
      Avast let's you earn the "Pro" version by sending texts, or emails to your friends.
      I received about 90 days of Pro protection thus far.
      CM is my favorite for day to day use.

    I've observed that AV apps on Android have a fairly significant impact on battery life, albeit moreso on low and mid-spec devices than on the high end where there's RAM and CPU cores to spare. I think it's a disservice at the moment to suggest that Android devices overwhelmingly need security software in the first place. Resident scanning is mostly just a waste of resources for the overwhelming majority of Android users.
    I have observed Android devices loaded with malware, but they were owned and used by kids who had actually gone through the trouble of side loading hacked applications in the first place. Ironically, two of those devices did have malware on them. It either wasn't found or was deliberately ignored, leading me to the conclusion that this is not a problem for normal humans and also that the security software doesn't work very well in the first place.

    • Dan Price

    Android has evolved far enough for me that as long as I use a device with a stock or near-stock OS (so that I don't have to remove pre-installed bloatware) I no longer feel it necessary to root. I do, however still sideload an occasional app that I am not entirely trusting of (Show Box for example) so I am still waiting to be authoritatively convinced I don't really need antivirus software. For now I use and like Avast, which I also used on Windows when I was still using it. Still, I would prefer not to use it because it must impact performance. Right now on my Nexus 7 with Android 5.1, Avast is using 260 MB of RAM (more than anything else) and on my Moto G it is using 26 MB of RAM (in the top 3).

    • Dan Price
      April 27, 2015 at 4:47 pm

      I'm not sure about whether anti-virus apps impact performance too much... I suppose they must, but it's hardly noticeable. I use Avast too - you must be a man of good taste :)
