Best antivirus for Android 2019: Bitdefender, Norton, Kaspersky and more
Android phones need security protection, but which is best for you?
There are more potential malware strains around than ever before. And, with people gradually shifting from desktop to mobile devices for both work and day-to-day browsing, the need to protect your portable devices has never been greater.
Smartphones are so integral to our work and home lives now, serving as our everyday companion. We use them for banking, for writing and creating files on the go, accessing company documents and then gaming and consuming media in our downtime. They're as functional as any device, and therefore it's vital they're protected from security threats as much as a desktop computer or laptop is.
Although it's generally easier to spread malware through networked computers rather than mobile devices, it's essential you have sufficient security in place to make sure you don't fall victim to malicious activity.
As a widely used and an open source platform, Android is unfortunately extremely prone to attacks. The platform has appeared on most vulnerable software lists regularly and although Google is attempting to clamp down on dodgy malware-toting apps, some still slip through the net and can easily be exploited by hackers.
Android users have been hit by a number of cloak and dagger attacks recently, in which seemingly innocuous applications are downloaded from legitimate sources, only for them to contain malicious codes.
Google has been criticised in the past for failing to properly vet the applications it hosts, particularly as some have been found to record keystrokes, silently unlock phones, and facilitate phishing attacks.
Whether or not you're running your device on the latest version, we've listed below the best antivirus software you can use to protect your Android-based smartphone or tablet.
Sophos Mobile Security for Android
It will scan your device for known-to-be malicious or unwanted applications and will alert you to any it thinks could be used to steal your data or use a lot of your data, helping to protect your information and also, your bank balance. It also features a built-in data wipe tool that means if your phone is lost or stolen, you can remotely wipe any sensitive information or you can instead choose to lock it so no one can access that data.
One of Sophos Mobile Security for Android's more impressive inclusions is an Authenticator that allows you to add multi-factor authentication passwords for some of the most widely used services, such as Google, Amazon and Facebook. You can also block access to other apps using a password, so if, for example, you share a device with your children, you can prevent them from being able to open your work-focused applications.
You can also block nuisance calls using Sophos' antivirus and if your company uses Sophos Mobile or Sophos Central, the IT department can track your device remotely for any threats too.
And all this comes without a cost for the basic, ad-free consumer version.

McAfee Mobile Security
McAfee is perhaps one of the most well-known names in antivirus software and it's no surprise the company has adapted its anti-malware and antivirus platform for Android devices.
Called McAfee Mobile Security: Antivirus, Wi-Fi VPN & Anti-Theft, the antivirus has been created specifically for the Android platform, with a free tier and a premium add-on, although there's little extra in the paid-for version that'll convince you to pay 2.49/month (29.99/year).
On top of the app's excellent real-time protection and malware defence scores as tested in an AV-test, it also boasts a few security additions that make it a worthy entry on our list. For example, if your phone's stolen, you can track where the thief has taken it and use the camera to covertly take a photo of them, too.
You can PIN-protect apps if you want to stop intruders breaking into those that hold confidential information, or even seeing them in your apps list and Android Wear integrations, allowing you to lock the handset if it moves too far from your watch.
If you do want to take advantage of McAfee's premium features and you're happy to pay the 2.49 extra, you'll get 2GB cloud storage and phone support if something goes wrong, but neither really justifies the fee in our opinion.

Bitdefender Mobile Security & Antivirus
Bitdefender is one of the few security companies that doesn't offer a free tier for users of its Android app and while that may immediately turn some users off, there are some great features here for those who are willing to shell out a bit.
Web protection and PIN-locking for apps are both present and correct, but a couple of interesting touches help the latter to stand out. You can automatically disable PIN-locks for apps when connected to home WiFi networks, and it will even let you snap a picture of anyone who tries to guess the PIN for any locked apps.
Bitdefender's anti-theft tools have some unique attributes, too. Your device can be tracked and controlled via SMS, and there's even the option to silently call it so you can listen in to any potential thieves.
Privacy modules will scan your installed apps, to make sure there's no sneaky software claiming more permissions than it should be, and Android Wear integration alerts you any time your phone loses connection, helping prevent any accidental losses.
In terms of protection, Bitdefender's software racked up a perfect score in both of AV-Test's measurements. It's a great choice if you're willing to part with some cash in exchange for peace of mind, and there's even a 14-day free trial to help you make your mind up.

Avast Mobile Security
Avast's desktop offering is a favourite of PC users and for good reason. Its protection rating is excellent and the company's mobile offering is no different. According to AV-Test, Avast Mobile Security got full marks for malware protection and dropped by just 0.1% in real-time defence.
It's offered as a free version, which is more bare-bones than some other examples. Automatic scans can only be set up to run once a day, and PIN protection is limited to your settings, the Google Play store and one app of your choosing.
It's also crammed with ads, both for third-party services and for Avast's other products, most of which are not included in the free tier. These can get particularly obnoxious and the Avast ads are often hard to distinguish from features included in the app by default.
These can be removed with a pro subscription - along with the one-app PIN protection limit - but it's a little disheartening to see Avast gate off something that many antivirus services offer free as standard.
One feature that does go a long way towards making up for this, however, is the custom firewall setting. It requires a rooted device, but if you've already rooted your phone it will allow you to block certain apps from using the internet, or set them to only use WiFi connections rather than mobile data.

AVG AntiVirus Free
Another well-known name in the PC AV market, AVG's mobile offering is something of a mixed bag. It's another ad-supported app, but AVG's implementation of ads is particularly offensive. Putting ads on the Android lock screen is an egregious misstep and although you can disable this, it should never have been put there to begin with, in our opinion.
Protection was also somewhat lacklustre - while it detected 99.1% of previously-known malware, it only managed to pick up 96.2% in the real-time tests. While this might sound like an excellent result, it's lagging slightly behind both the industry average and its nearest competitors.
Where it makes up for this, however, is in features. Apps are scanned on download, device scans can be scheduled on a daily or weekly basis and a basic WiFi scanner is bundled to analyse your network for vulnerabilities.
Web protection is also available, as is an anti-theft toolkit including remote lock and wipe functionality, location tracking and the ability to sound an alarm from your phone. If you have multiple devices, you can use AVG Zen to manage all of their antivirus settings remotely, too.
Along with getting rid of the ads, moving up to a pro subscription gives users some nice additional features, such as device and app locking and a Camera Trap, which snaps a picture of anyone attempting to unlock your phone and emails you a copy.

Kaspersky Mobile Antivirus
Kaspersky has an excellent reputation in enterprise security, so you can be assured of excellent protection from its Android app. Sure enough, it got a 99.9% score in AV-Test's protection benchmarks.
Unfortunately, its free version is somewhat hobbled by a lack of features. There's no automatic scheduling for scans, which must be manually triggered and it won't automatically scan downloaded apps, either. There are anti-theft features which let you take remote photos though and it will alert you of the phone's new number if the SIM card is changed.
The paid subscription, on the other hand, is a different story. This unlocks a full suite of scheduling options for malware scans, as well as real-time protection, browser defence and even a feature that protects against SMS-based phishing scams.
Calls and texts from specific numbers can be blocked too, and you can hide certain contacts from appearing in your address book. Be warned, though, as these features are only guaranteed to work on Android 4.4 KitKat and may not work on newer versions of Android.

Norton Mobile Security and Antivirus
While Norton's mobile antivirus is a very well-rounded package, its most useful feature by far is the App Advisor. This scans your installed software looking for untoward behaviour and while other security products do offer this, Norton goes into much more depth.
It looks for unnecessary permissions and also examines location tracking, ad display, automatic updates and excessive power and data use. It even integrates with Google Play, letting you know whether or not an app is safe before you download it.
Sadly, this feature's only available with a paid subscription - which at 30 per year is significantly steeper than most of its rivals. On the bright side, this does cover unlimited mobile devices, so if you're looking to manage the security of an entire team it could work out cheaper in the long run.
The free version isn't too bad, either. Although you won't get access to the App Advisor, free users will be able to schedule daily, weekly and monthly scans, with a standard suite of anti-theft measures and a SafeSearch tool that flags results as trustworthy or untrustworthy.
App-locking isn't included at all, but since Norton offers a separate, free app for this purpose, we're not going to deduct any points for not bundling it.
Price: Free; Premium subscription 29.99/y
