Considering how often malware, ransomware and hacking hit the headlines, you might be wondering which anti-virus is best to keep your trusty Android phone and all its data safe. So we've put together an updated list of apps for keeping your device protected. Whether you are looking to keep your phone safe from theft or a trojan, these are the best antivirus and security apps for Android in 2016 and 2017.
1. CM Security
CM security (Clean Master) is an all-singing, all-dancing option made by Cheetah Mobile that brings you a whole host of anti-virus and security features for free - as long as you don't mind a few ads. Or you can pay $.99c each month to remove them.
Feature-wise it tries to offer everything - anti-virus, browsing protection, battery saving, privacy protection of apps, the whole lot. It takes pretty much the same simplified approach to each of those things too. CM security identifies what it describes as threats and then asks what you want to do about them in a straightforward way.
That might disappoint people who love spending time in settings menus, but you're not going to be doing that with CM Security. One potential drawback, however, is that it's relentless in nagging you about other aspects of your device and other apps made by Cheetah that can help you out. But again, it's free, so it's hard to complain too much.CM Security Master App Lock
Kaspersky Internet Security
Kaspersky is a well-established anti-virus and security package on the desktop, and with its Android app it brings a whole lot of that protection to your mobile. That means you get anti-virus, call and text control, anti-theft, and anti-phishing features.
It can also protect you with real-time, web protection, and a few privacy options, though to get the full package you'll need to pay for the premium version of the app, which is currently priced at $14.95 for one year. If you need to cover more than one Android device, you can add up to two more at $5 per device, per year.
If you want to test out the premium features, there's a 30-day trial to activate within the app, but to use some of the features you will need to create an account using your email address. The anti-theft feature, for example, isn't premium but does require an account to work.Kaspersky Antivirus & Security
Malwarebytes is one of our favorites in this list, for a couple of reasons. Firstly, it focuses on doing one job well - protecting your phone from malware - and secondly, because it does so with a simple interface and well-chosen options.
That means it's also relatively lightweight in comparison to the others here, and offers free real-time protection. As well as offering malware protection, there's also a really handy privacy audit feature that scans all the apps on your phone and breaks them down into different categories, which allows you to get a simple and quick overview of all the apps on your phone.
You'll probably want to pay some attention to categories like 'Apps that can cost you money'. The security audit feature does a similar thing for your phone settings, by quickly assessing potential weak spots in your security and guiding you to turn them off. This is likely to include things like switching off the ability to install apps from third-party sources and the developer options.
There's no longer a phone location feature, as many of the others offer, but then there's also not really any need for one given that Android can do that natively. Malwarebytes might not offer the same level of features as some, but it's a well-thought out, and free, option that does its job well.Malwarebytes Anti-Malware
Avast Antivirus & Security
Avast's anti-virus and security package is one of the most feature-packed in this list. If you want an app that can take care of all your security, RAM boosting, junk cleaning and other needs, Avast could be it.
Some of those features will, as with similar apps, require the installation of other components too though. On the purely protection side of things, Avast has the on-demand and real-time scanning you'd expect of an anti-virus app, and also includes things like the ability to check the security of your current WiFi connection and to lock specific apps so only you can open them.
There's also a firewall option, but to use that you need to have a rooted phone. Unlike some of the others in this list, the display ads that show in the app aren't too off-putting, but it does promote a lot of its own other apps designed to 'enhance' the suite. If you don't need or want those features, that could be slightly annoying to ignore constantly. If you want no display ads at all, you'll need to pay for the premium version, which is available on a monthly or annual basis and varies in cost depending on where you're located.
If you do decide to pay, each subscription is valid across all your Android devices using the same Play Store account. Add in a call blocker and app privacy advisor that displays all the info in a simple, easy to understand way and Avast is a truly useful anti-virus tool for anyone looking for an 'all in one' package.Mobile Security & Antivirus
AVG Antivirus Security
AVG Antivirus Security is more than its name suggests, as it also provides app locking, anti-theft, task killer and app backup features. And it does it all in a well-designed interface. There are also a few battery-saving options on board, and the ability to dig down into your battery data to find out what's been draining it.
The power saving options replicate functions dotted around any stock Android settings menus, but bring them altogether in one place for easier control. If you want to use the junk cleaning options, you'll need to install AVG Cleaner too, but once you have, it integrates with AVG Antivirus.
In this instance, it seems smart of AVG to provide the cleaner functionality through a separate download, rather than bundle another large app inside the main suite. It's worth pointing out that AVG Cleaner is free to download, like AVG Antivirus, but also offers another paid for upgrade to a Pro version for additional features and the removal of ads.
You don't need the premium version of either app to use the Phone Locator option, but you will need to sign up for an account via your email address to use this feature.
Lookout is one of the apps on this list that doesn't have a desktop client, as it's focused exclusively on mobile. It's also one that requires you to sign up for an account to use any of the features.
Once inside, you've got the choice of taking the free or premium route - premium is around $2 per month. The free version gives you just app security and phone location features, whereas premium will also protect your Web browsing, give you a privacy overview of your apps and allow a few other anti-theft related features.
There's also a handy breach report feature that will alert you if any of the services you use are hacked, thereby allowing you to change your credentials in a timely manner. If it doesn't sound like the free version offers much, that's a mistake.
Within the single category of app security, you're protected against adware, bots, click fraud, remote exploits, root enabler threats, spyware and a number of other types of malicious software.Lookout Security & Antivirus
McAfee Mobile Security
McAfee is a long-established name in the security space on the desktop, and its Android app provides the level of features you'd expect to find from a premium brand.
As well as giving you on-demand and real-time threat protection, there's a feature to check your data exposure via installed apps, as well as more traditional options to lock certain apps away from prying eyes. Other features, like device backup options, the 'Find device' mode and specific profile options require some additional permissions and email registration before you get access.
It's a relatively expensive option if you want access to the premium version, however. At $29.99 each year, it's twice as expensive as some of its competitors, though closer in price to something like Lookout Premium. Can't say it's likely to win any design awards though.McAfee Mobile Security
Norton Security Antivirus
Norton Security Antivirus is another hugely popular desktop protection platform that's made the jump across to mobile. In short, it blocks and removes malware both on-demand and in real-time.
It also offers the now-familiar app advisor feature that tells you about privacy risks in a simple, easy to understand way. One thing that none of the others offer but Norton does is a really handy feature that integrates with Google Play to show you any alerts about an app before you download it; so you can see if the app you're about to install hogs battery, uses excessive data or poses any other sort of potential risk.
There's a 30-day free trial for the premium version, which unlocks all the features, but after that it'll cost you $29.99 per year, making it on a par with McAfee in terms of pricing. It does have an appealingly simple design and is straightforward to use though.Norton Security and Antivirus
