The best Android antivirus apps go beyond finding and removing the latest malware to stopping phishing attempts, flagging fraud attempts, protecting your identity and letting you securely communicate with a VPN.
While they often cost less than AV protection aimed at computers, Android security apps are still an investment at between $15 and $50 per year. While most of the best Android phones come with Google Play Protect pre-installed, it continues to lag behind paid Android antivirus apps when it comes to finding and killing viruses. To get top malware performance, many people turn to a security suite like the ones on our best antivirus software guide that cover all of a family’s computers, often at a bargain-basement price.
What follows is a bird’s eye view of the top antivirus and security apps for Android. The contenders range from Avast Mobile Security, Bitdefender Mobile Security and ESET Mobile Security to Google Play Protect, McAfee Mobile Security, Norton 360 for Mobile and Trend Micro Mobile Security. All offer malware scanning, although with varying degrees of speed and success.
The top guns, however, aim for wrap-around protection of not just your phone or tablet but your data, privacy and online identity. Here are the best Android antivirus apps you can get right now.
The quick list
1. Bitdefender Mobile Security
By putting together everything from top malware protection, app anomaly detection and phishing protection, Bitdefender Mobile Security is nothing short of the best way to protect an Android phone. The antivirus app is a bargain at $25 a year but lacks an unlimited VPN.

Avast Mobile Security not only does the basics well with good malware protection but adds an app guard and scheduled system scanning. Its ad-sponsored free version may be limited here and there but can be alternative protection to Play Protect.

Good malware protection is stacked on top of an unlimited VPN, an App Advisor for checking on the safety of software, AI-based scam protection and a slew of other protective elements. This makes Norton 360 for Mobile a one-stop security center for mobile devices.

4. McAfee Mobile Security
As is the case with many of its other security products, McAfee designers have gone out of their way to make Mobile Security visually appealing and easy to use with a simple interface that delivers essential defenses. It adds full VPN access and a password manager.

With the fastest phone scanning around, ESET Mobile Security can trap malware, new and old, as well as phishing attempts, all while analyzing Web sites for dangers. It’s a bargain but ESET’s scanner is among the hungriest around, potentially slowing an older phone.

By burrowing into the operating system, Google Play Protect not only provides a solid security foundation but includes things like a password manager. The good news is that it is already on your new phone or tablet, protecting it from all sorts of threats with improving accuracy.

7. Trend Micro Mobile Security
While the protection that Trend Micro’s Mobile Security provides is superior with a high-performance behavioral monitor, Ad blocker and secure browser, the app is resource hungry. This makes it hard to recommend for older mobile devices.

Best Android antivirus app overall
Bitdefender continues to dominate security software with its powerful Mobile Security app for Android. The software not only yields excellent malware protection but is one of the least expensive defensive apps around.
While its scanning placed a heavy load on the system’s resources, Mobile Security found just about every threat thrown at it and has no shortage of extra defenses, like the App Lock can turn off apps that might pose a security risk and the App Anomaly detector uses machine learning techniques to thwart unexpected and potentially dangerous actions. In addition to blocking objectionable online destinations, its Web site protection focuses on phishing attempts.
There’s not only anti-theft protection that includes GPS tracking and an annoying alarm but Mobile Security’s Account Privacy checks for compromised email accounts. While Mobile Security’s VPN blocks malicious websites and ads, its use is limited to 200MB a day; to get unlimited VPN use, you need to upgrade to the Premium Security package.
At $25 a year, I miss an unlimited VPN but Bitdefender Mobile Security is one of the least expensive ways to protect a phone or tablet. It’s the best mix of protection, price and performance for keeping your phone yours.

The best free Android antivirus app
Avast Mobile Security starts with a surprisingly fleshed out free version to protect phones from the most prominent threats while securely storing up to 10 of your favorite photos in the cloud-based Photo Vault. Unfortunately, you’ll need to put up with a flood of ads, popups and banners.
That said, the $20 Premium Mobile Security is an inexpensive way of getting rid of the ads that includes unlimited photo storage and lots of security-conscious extras. In addition to scan scheduling, Avast’s Web Shield helps avoid nasty Web sites and the Secure Browser lets you hide your identity online.
Avast Mobile Security’s Messages section does a good job of putting all outstanding security issues in your face. Should an app go rogue, Mobile Security’s App Lock can shut it down, cutting off its online oxygen
Need more? Ultimate Mobile Security costs $40 and ups this protection with unlimited use of Avast’s SecureLine VPN for secure online work and play.
Overall, Avast Mobile Security’s protection is good with the ability to stop popular and fresh exploits but at the cost of several false positive readings. Unfortunately, all these defenses add up to Mobile Security absconding with lots of system resources.

The best Android antivirus app for features
Norton 360 for Mobile attempts to provide nothing short of the most thorough protection you can get to defend a phone or tablet. It generally succeeds with perfect malware effectiveness scores on AV-Test’s battery of viral assessments but that’s only half the story because there’re no results from our other independent malware appraisal lab.
In addition to thorough scanning, Norton 360 for Mobile’s App Advisor takes a proactive approach by warning of dangerous software before it can be installed on a phone. The app’s Privacy Monitor works with data brokers to keep your personal information (including banking details) off the dark Web while Norton’s Genie AI can warn about artificial intelligence scams.
The app’s VPN access is part and parcel of Norton 360 for Mobile not a separate app making it easier to use. Unfortunately, unlimited access costs an extra $50 a year on top of the Norton 360 for Mobile’s $30 a year subscription, making it a steep upgrade.
That said, Norton 360 for Mobile is the rare Android security app that can safeguard recent Chromebooks along with Android phones and tablets. This makes it a great way to protect computers at home, at work and at school.

The best Android antivirus app interface
A full-service suite for phones and tablets, McAfee Mobile Security is for more than just getting rid of infections. It’s like having a mini security suite for Androids.
Based on one of the best security interfaces around, everything is visual, simple and straightforward. The app offers good protection from a variety of threats with AI-based cloud scanning that can be scheduled, while its Safe Browsing can alert you to dangerous Web destinations. It can block the installation of unwanted apps.
McAfee Mobile Security goes a couple steps further with protection against unsafe email attachments, online identity monitoring and scams. Unlike its peers, it has a password manager for securing your login credentials.
On the downside, Mobile Security’s scanning can be painfully slow and based on AV-Test’s survey, it allowed several new threats to get through its defensive screen. Happily, Mobile Security didn’t have any false positive readings of safe software. McAfee didn’t, however, participate in our other independent malware lab’s testing.
At $30 a year with unlimited VPN access and an integrated interface, Mobile Security is a bargain at half the cost of comparable protection. It might not be perfect, but McAfee Mobile Security does a lot for a little.

The best Android antivirus app for fast scans
Sure, there’s a free version of ESET Mobile Security, but the sweet spot for this phone and tablet security app is the $15 Premium version. It not only gets rid of the annoying ads but increases the app’s protection profile with quick scans.
Its emphasis is on stopping phishing attempts dead in their tracks while the real-time system behavioral analysis looks for changes that might be due to malware. Any app can be locked and Mobile Security’s secure Payment Protection browser can help keep your identity and credit card info safe, but its unlimited VPN is only available with one of ESET’s security suites.
The app can show the GPS position of a lost or stolen phone, surreptitiously snap a photo of the person using it and lock it remotely. That said, Mobile Security’s Scanning engine goes beyond the expected to look at system software, apps and data for threats. It can even spot Windows and Mac viruses.
In addition to monitoring Web sites for potential malware exposure, ESET has a built-in security barrier for rogue code on social media apps, like Facebook and Instagram. Overall, its protection was excellent but its lightning fast scans can slow a phone down.

The best pre-installed Android antivirus app
If any app deserves the most improved award, it’s Google’s Play Protect. It has risen from barely being able to find dangerous software to half-step away from the best.
Built from the start into the Android operating system, Play Protect resides several layers below the other Android security apps, allowing it priority access to the system’s inner workings. Play Protect and the system software team up to block malicious sites and dangers lurking in some of the major social media apps.
Able to stop unwanted apps from being installed on the system, Play Protect scans for app problems but not phone data. Based on a combination of local and cloud analysis, scans can’t be scheduled but will start up automatically during idle periods.
Part of the software for billions of phones and tablets, Play Protect raised its virus detection rate to world-class levels. With results in the 99+ percent effectiveness range, Play Protect’s scanning engine is capable but still allows potential threats through with too many false positives.
Like Microsoft Defender, Google Play Protect comes preinstalled, resides in the background and protects from day one. In other words, it’s the do nothing approach to security that actually works.

The best Android antivirus app for banking
The proof of a security app’s usefulness is in its ability to thwart creative and novel threats and Trend Micro Mobile Security punching above its weight class. At $30, it lacks a VPN and several other security enhancing amenities but includes the company’s Secure Guard hardened browser to help make online commerce safer.
The app can not only block ads but its Web Guard warns of dangerous sites. Too bad, it can’t schedule scanning and getting the VPN requires subscribing to one of Trend Micro’s security suites. It is capable of removing unused apps on your phone or tablet and Mobile Security is the rare Android app that focuses on the privacy settings for major social media accounts.
Meanwhile, Mobile Security’s Fraud Buster feature warns of potential online scams and a lost or stolen phone can be located and locked. The app includes parental controls and a Wi-Fi network scanner.
Unfortunately, all this adds up to a heavy burden placed on the system’s resources, although Mobile Security was just as good at detecting AV-Test’s and AV Comparatives’ viral samples. Its proliferation of false positives shows that Trend Micro Mobile Security might have been a little too eager to please.

Why you should use an Android antivirus app
In order to keep your Android smartphone or tablet safe, you should keep its software updated to the latest version. This is because each new version of Android is more secure than its predecessor, and each monthly Android security update fixes newly found flaws.
However, unless you have a Google Pixel or Android One phone, you won’t get these updates and upgrades right away. Most device makers need extra time to make sure that changes to Android won’t break their devices or software.
The time between updates can be a couple of weeks though it can also take months. To make matters worse, some Android phones stop getting Android OS upgrades after two years and a few never receive monthly security patches at all.
This is where the best Android antivirus apps come in. They stop attacks that try to get around Android’s built-in defenses, especially those that Google has patched but your device doesn’t have yet (or never will). They also stop new attacks that Google Play Protect won’t catch, even on Pixel devices.
How to choose the best Android antivirus app for you
Which Android security app you get depends as much on your budget and online lifestyle as on whether you want VPN access and extras, like a password manager. Our opinion is that these can be valuable tools for isolating your phone from the wilds of the Internet, potentially saving the system and your online identity from harm.
There’s a lot for cheapskates, like the pre-installed Google Protect. It can do a lot to keep a phone or tablet clean of infections, but it’s only a start because its protection allowed several potential threats through. In fact, Avast Mobile Security’s free version does a better job of defending a phone but its ads can be annoying. Its paid versions are hassle free at $20 for the Premium version, although the $40 Ultimate version adds VPN access.
That said, McAfee Mobile Security not only has the best interface for a security app but includes unlimited VPN use as well as security enhancing add-ons like a password manager. It’s all included for $30 a year.
Norton 360 for Mobile takes this a step further with the combination of a VPN and a comprehensive approach to online safety. It costs $30 a year but the VPN access adds to the total.
Both Trend Micro Mobile Security ($30 per year) and ESET Mobile Security ($15 per year) have more in common than their names. Both are resource hogs that can potentially slow down an older phone. The former has extra phishing protection while the latter has a behavioral monitor.
That leaves Bitdefender Mobile Security as our choice for the best mobile security app based on its superior virus protection and wide variety of dedicated defenses against threats, old and new. It’s a bargain at $25 a year and would be vastly improved with full VPN access.
How we test the best Android antivirus apps
To rate these Android security apps and pick the best from the also-rans, we subjected each to a comprehensive round of testing on a OnePlus 11 test phone. It started with the installation process and extended to examining every major feature (and a slew of minor ones) until we had a good idea of how they worked.
To measure each app’s passive impact on performance, we used the Passmark 11’s system performance benchmark before and after the app was installed. We ran it again with the phone scanning for dangers and compared the three readings.
We also used a stopwatch to time how long it took for each app to fully scan the system for threats. In these tests, smaller numeric results indicate better performance.
To gauge the security protection offered by each of these Android apps, we turned to two independent malware test labs. In addition to AV-TEST we used data from AV-Comparatives on each app’s ability to spot and destroy a variety of threats. We paid particular attention to false positive readings of safe software that the apps thought was dangerous. Together they give a good idea about the app’s effectiveness at catching malware, new and old.
