Should you install an antivirus on your Android device?

We're often asked whether its necessary to install an antivirus an Android smartphone, and with good reason. Apple has tried to discredit Android by presenting as a system infected with viruses and malware. The flaws that have come to the surface in recent years haven’t helped to reassure Android users. Those who have used their computer without an antivirus will be able to back this up: the results can be dramatic, except for those more knowledgeable users who can manage to escape unscathed. So, should you be suspicious of malware, viruses and Trojans of any kind on your Android device?

Are there risks if you don’t install an antivirus on your Android device?

Until now, very few Android devices have had viruses - at least if you compare them to the number of computers that have been infected with them. This doesn’t necessarily mean that an Android smartphone or tablet is invulnerable. Mobile web browsing has seen an unprecedented increase in virus activity, and we are already aware that any mobile internet browsing has risks. Recently, the danger of infection by a virus is more likely with Trojans like Obad which have quickly gained the reputation as the most dangerous virus that has ever been identified. It will not be the last.

Is Android more vulnerable than Apple’s iOS?

We often hear that Apple has no virus problems and that it’s not necessary to install an antivirus on Android. This is both true and false: Apple is a more closed system than Android, therefore it is much more difficult to enter the system to develop a virus. As a result, it's logical that these virus developers opt to target Android’s open system. The intrinsic functioning of Android has it faults, and its these faults that are used by the viruses. That said, iPhone users are much less vigilant of viruses than other users but they are also vulnerable.

Is the Play Store a safe bet?

Yes and no. In theory, Google has deleted and forbidden any applications which contain viruses or spybots. Unfortunately, this filter isn’t foolproof: we saw it with the number of false versions of iFruit (GTA) to emerge when Android users were waiting for its release to their devices. The Google Play Store cannot be completely trusted. Some advice: before installing an application look at the number of downloads and the number of positive comments for the app, but also the authorizations. This is a good strategy for Android users to determine whether an app can be trusted.

That said, the new algorithm implemented by Google is now able to more efficiently filter the Play Store, that way users don’t encounter any nasty surprises. Again, be careful of what you download. Often a malicious virus can be hidden in an application that looks kosher, but it’s not. It’s important to check the name of the developer or the business that edited this application, as well as the number of downloads, comments and authorizations.

What is at risk if I find a virus?

The main risks aren’t very serious but they can be problematic for some: gathering your personal data and redistributing this information. That is best case scenario. You could also lose all your data, find an application that empties your battery or find yourself with corrupt files. If you consider the fact that our phones often contain much more personal information than our computers (phone numbers, email addresses, photos…), there’s no doubt that the risk of such an attack is much more dire for mobile devices.

How can a virus get onto my device?

Many everyday tasks can be dangerous for your Android device: from downloading an app to reading your emails or even by simply surfing the net. But its not all about the internet. It's also possible for viruses to be transferred via Bluetooth or Infrared if you find yourself close to an infected device. This could happen when you're out in public, at a friend's place or even in your own home. 

The distribution of viruses can be much quicker than on a computer, as we can carry this virus in our pockets everywhere we go. It’s advisable to regularly run a check with an antivirus.

What are the disadvantages of an antivirus on Android?

One of the main criticisms about antiviruses is that they play on fears about viruses, as they require full access to all user data on a device. Essentially, they do exactly the same thing as the viruses you are trying to avoid… and you need to have confidence in your antivirus. Some antiviruses are also energy intensive: they are always running in the background and are not always optimized for batteries. It’s often the price you'll have to pay to be protected… Finally, an antivirus will not always be 100% effective. While some like Avast, Kaspersky or Lookout find 90% of viruses, others like McAfee will detect only a few of the dangers.

Which antivirus should I choose for Android?

This will largely depend on how you use your device, even if the overall protection and services offered by the antiviruses are the same. We recommend Avast Mobile Security & Antivirus, AVG Mobile (smartphone and tablet) or Avira Antivirus Security. Don’t forget that an antivirus that scans constantly will affect your battery life. You’ll probably need to adjust how you use your device or at least make sure that your antivirus isn’t too demanding. Don’t hesitate to try out a few different antiviruses to see which one works best for you.

    Very Very Best Avast antivirus I am using for 1 year ago best performance

  • Dejan Jandric Jan 7, 2017 Link to comment

    In my experience, and I work with mobile phones, those antivirus apps are bad, too much scam spam and not helping a bit. Best to have is a phone with normal apps (such as Fb,Inst,WhatsApp) .

    As long as you can turn off certain components that keep battery draining task to a minimum, that's the one to use.

    I have been using Avast for 2 weeks now and was getting a pop up to install a clean up app from the same company every time I open my screen. I've deleted it and the pop up has gone with Avast.This was quire annoying. Pop up could be removed by swiping it to the left.

    I use malware bytes as I do on my computer. No problem as it is an app I trust

    A couple of years ago 360 Security seemed to be the only thing that a Droid X2 would run. I have been using Macafee since I pay for it with my insurance. Avast was light on a old computer but would crash the Droid. I also use Malwarebytes and swappable batteries are a plus, battery life is not really a problem with the already heavy use I put on this pocket computer.

    I'm just an ordinary, retired geek who's used Android for years with virus detection. Got tired of battery issues. Stopped using virus scanners a year ago with no issues. Much better battery life.

      Hi five "geek" 😆 I did the same just like you one year ago and still never any virus problem.

      • Brittany McGhee Dec 20, 2016 Link to comment

        Lawrence & Jerry,
        Thanks for the comments, fellow geeks. Which virus detection apps have you guys tried previously that drained so much battery?

      • Jerry's W. Dec 21, 2016 Link to comment

        I tried Avast in 2013 for only reason I had rooted the phone and liked the option in Avast for having rooted it you could enable firewall. Those days avast was great and not much interference from Avast. These days it's annoying and ugly ui.
        I tried several more but concluded for android no antivirus is nessesary simply for its Android. Being careful when installing apps beside Google play store and paying attention when surfing the internet is enough to not getting any " infection".
        Rooted this Samsung s5 kccat6 sm-g901f and using xposed firewall helps me where I want to be feeling safe.
        Rom/systembackup with TWRP every day makes it possible to set back to restore point of the whole phone incl data.
        Pro: no battery-sucking unnecessary " antivirus" app
        Con: Daily 10 min of my time making systembackup.

    I've used CM Security for years without any issues. Will try Avast though to see how it compares. Used AVG prior to CM but didn't like it (that was over 2 years ago though).

    As an IT technician I use avg antivirus and have had really good experience which I am glad to say has followed over to android as well

  • Albin Foro Dec 19, 2016 Link to comment

    My experience with PCs, professionally engaged with other users exchanging and collaborating on files that triggered AV alerts, led me to install anti-virus on Android devices. Currently BitDefender on all systems, but a quarter century of experience teaches brand loyalty is foolish, they're only as good as this year's lab test results. BitDefender is quiet and invisible, low on resource requirements, simply scans software downloads and storage when needed - it's reassuring whenever Android security emergencies hit the media to know that a service is probably already on it. (Note that I don't want a commercial account with Google, and sideload APKs for paid apps from good sources - anybody sideloading outside the Play Store should have protection.)

    I don't think the current Android system of security and system updates, at discretion of OEMs and telcos and leaving billions of users constantly behind, is sustainable - eventually Google will have to assert control over operating system updates as Microsoft and Apple do.
