10 Best Free Antivirus Apps for Android in 2026 (Tested Against AV-TEST Results)
Google Play Protect comes installed on every Android phone with the Play Store, and it’s genuinely gotten better over the years.
But independent lab testing still shows a real gap: in AV-TEST’s most recent rounds, Play Protect scores around 5.5 out of 6 for protection, while a dedicated antivirus app typically scores a perfect 6/6. That half-point gap is the difference between catching a threat and missing it.
Quick answer: Bitdefender Mobile Security is the strongest genuinely free option overall, with Avira close behind for its wider feature set. If you’ve read that Norton is a great free pick, that’s worth double-checking, since Norton no longer offers a real free tier in 2026 (more on that below).
We checked each app below against its current Google Play Store listing, official pricing page, and the latest AV-TEST and AV-Comparatives lab results, rather than relying on older reviews that may no longer reflect what these apps actually offer for free.
Quick Picks: Best Free Android Antivirus Apps at a Glance
| App | Best For | AV-TEST Score (2026) |

How We Evaluated These Apps
We checked each app’s current Google Play Store listing and official pricing page directly, cross-referenced protection scores against AV-TEST’s May 2026 mobile security report (their most recent published round at the time of writing), and flagged any app whose “free” positioning has changed, like Norton’s shift to trial-only.
This matters more than it sounds. A2021 review calling an app “the best free option” can be quietly outdated if that app moved to a subscription model since.
Something Worth Knowing Before You Pick: Who Actually Owns These Apps
A few of these brands aren’t as separate as their names suggest. Avast, AVG, Norton, and Avira are all owned by the same parent company, Gen Digital (formed when NortonLifeLock and Avast merged in 2022; Avast already owned AVG, and had acquired Avira in 2021).
That doesn’t automatically make any of them worse, but it does mean their core scanning engines share more DNA than you might expect, and it’s worth knowing before assuming four “different” free apps give you four genuinely independent opinions on a file.
Bitdefender, Kaspersky, ESET, McAfee, Trend Micro, Malwarebytes, and Sophos remain independently owned.
It’s also worth knowing that Avast settled with the US FTC in 2024 over past data-sharing practices through a discontinued subsidiary (Jumpshare, shut down in 2020), which sold anonymised browsing data.
Avast has since changed its practices, and the issue predates the current app, but it’s the kind of trust-and-safety history worth being aware of for a security app specifically.

Best Free Antivirus Apps for Android in 2026
1. Bitdefender Mobile Security: Best Overall
Bitdefender’s free Android app consistently posts near-perfect scores in independent lab testing, and it does so while staying genuinely lightweight. Its Autopilot feature handles most security decisions automatically, so new apps are scanned the moment they’re downloaded and your storage gets checked when your phone is idle, without you needing to configure anything.
The engine runs primarily in the cloud, which keeps CPU usage low and means it doesn’t need to store bulky virus definition files locally, and it also doesn’t drain your battery the way some heavier competitors do. The free tier includes real-time app scanning, a malicious website blocker that works across most Android browsers, and even 200MB/day of VPN data.
The main gap in the free version is scheduled scanning; you can’t set it to run automatically at a specific time, only on-install and on-demand. For most users, that’s a minor trade-off given how quietly effective the rest of the app is.
Best for: Anyone who wants a “set it and forget it” scanner without constant upsell prompts.
Skip if: You specifically need scheduled scans on the free tier.
Price: Free, with paid upgrade for anti-theft, App Lock, and unlimited VPN | Platform: Android
2. Avira Antivirus Security: Best Free Feature Set
Avira’s free Android app punches well above its “free” label. Independent testing in 2026 gives it a perfect protection score, and unlike many competitors, its free tier isn’t stripped down to a bare scanner.
It includes the full malware scanner, an app lock to PIN-protect sensitive apps, an Identity Safeguard that checks whether your email has appeared in a data breach, and a privacy advisor showing which apps are requesting permissions they probably don’t need.
It also scans external SD cards, which some competitors skip entirely, and includes a smartphone tracker for locating a lost device. Given how much is included without a paywall, Avira has become one of the more recommended free options among independent reviewers in 2026.
Best for: Users who want the most complete free feature set without upgrading.
Skip if: You’re specifically prioritising the absolute lightest possible app on system resources. Bitdefender edges it out slightly there.
Price: Free, with paid upgrade for VPN and additional tools | Platform: Android

3. Kaspersky Security & VPN: Best for Anti-Theft Tools
Kaspersky’s free Android tier includes solid manual malware and virus scanning, along with a genuinely strong anti-theft suite: remote lock, remote wipe, and device location tracking are all included without upgrading. The free version keeps ads to a minimum and doesn’t aggressively push you toward the premium plan, which is a relief compared to some competitors on this list.
The trade-off is that the free tier requires manual scans rather than continuous real-time protection, and there’s no Wi-Fi network scanner or additional privacy tools on the free plan. A 30-day trial gives you a full look at the premium features (real-time protection, anti-phishing, app locker) if you want to evaluate before paying.
One note some Indian readers may wonder about: Kaspersky ceased consumer operations in the United States in 2024 following a government restriction there, but this doesn’t affect availability or support for users in India, where Kaspersky continues to operate normally.
Best for: Users who specifically want strong anti-theft tools without upgrading.
Skip if: You need continuous real-time scanning rather than manual scans.
Price: Free, with 30-day premium trial | Platform: Android
4. Sophos Intercept X for Mobile: Best Business-Grade Engine, Free for Personal Use
Sophos is best known for enterprise security, and its mobile app brings that same detection engine to Android users at no cost for personal use. It posts a perfect score in independent 2026 lab testing, matching Bitdefender and Avira, but it’s a name most casual users have never heard of, so it consistently gets overlooked in “best free antivirus” roundups.
The free version includes real-time malware scanning, a privacy advisor, and web filtering to block malicious sites, all without the ad-driven upsell tactics that some consumer-brand apps rely on. It’s a genuinely no-nonsense option if you’d rather have an enterprise-grade scanner than a feature-packed consumer app.
Best for: Users who want a business-grade detection engine without ads or aggressive upsells.
Skip if: You want a more feature-rich app with extras like a built-in VPN or system cleaner. This one stays focused on core protection.
Price: Free for personal use | Platform: Android

5. AVG AntiVirus Free: Best Budget-Friendly Value
AVG (a Gen Digital brand, alongside Avast, Norton, and Avira) has been downloaded more than 100 million times from the Play Store, and its free tier is genuinely well-stocked. Unsafe device configuration detection, RAM-hungry app and process identification, a full anti-theft suite, and phishing protection are all included without paying.
The premium tier adds social media security scanning, Chrome’s “Safe Web Surfing” integration, a battery drain monitor, and mobile data traffic monitoring. AVG also has companion apps in the Play Store, including AVG Cleaner and AVG Secure VPN, if you want to build out a fuller free toolkit from the same developer.
Best for: Users who want AVG or Avast-level features without picking between the two. They’re close cousins under the same parent company.
Skip if: You’d rather avoid apps from the Gen Digital family entirely for variety in your security stack.
Price: Free, with paid Pro upgrade | Platform: Android
6. Avast Mobile Security: Best for Extra Tools (With a Privacy Caveat)
Avast remains one of the most recognised names in this space, with a free tier that includes live scanning of installed apps, scheduled scan options, SMS and call blocking, a web shield against malicious links, and app-locking with a PIN. Feature-for-feature, it’s one of the more generous free tiers on this list.
Two things are worth knowing before installing it. First, the free version is genuinely ad-supported, and several users and reviewers have found the upgrade prompts more frequent than competitors like Kaspersky or Bitdefender.
Second, Avast settled with the FTC in 2024 over data-sharing practices tied to a subsidiary it shut down in 2020; the company has since changed its practices, but it’s relevant history for a tool you’re trusting with device-level access.
Independent 2026 test results on Avast’s real-world web and malware protection have been mixed across different labs, so it’s worth checking the most current AV-Comparatives or AV-TEST report before relying on it as your sole protection.
Best for: Users who want a broad free feature set and don’t mind frequent upgrade prompts.
Skip if: Data-privacy history is a dealbreaker for you, or you want a cleaner, ad-free experience.
Price: Free, with in-app purchases and premium upgrade | Platform: Android
7. McAfee Mobile Security: Best for Anti-Theft Extras
McAfee’s free tier includes real-time malware protection, device optimisation tools (battery booster, memory booster, storage cleaner), and a standout anti-theft feature called CaptureCam, which snaps a photo of anyone who enters the wrong PIN trying to access your device.
The premium tier adds VPN functionality, which is genuinely strong if you decide to upgrade, along with a URL screener and 24/7 tech support. The free version, like Avast, comes with a fair number of ads and upsell prompts, and malware protection has tested as solid without being class-leading in recent independent labs.
Best for: Users who specifically want the CaptureCam anti-theft feature.
Skip if: Ad frequency on the free tier is a dealbreaker for you.
Price: Free, with paid Standard tier for VPN and ad removal | Platform: Android
8. ESET Mobile Security: Best for Banking & Phishing Protection
ESET’s PC antivirus has a strong reputation, and its Android free tier carries that over well: basic antivirus protection, real-time device scanning, remote lock, remote alarm, tablet support, and a consolidated security activity log are all included at no cost.
Where ESET stands out is anti-phishing protection specifically, integrated directly into your mobile browser to block known phishing sites before you land on them. If you do a lot of banking or shopping from your phone, this is one of the stronger free-tier phishing defences on this list.
The premium version adds App Lock, proactive anti-theft, scheduled scanning, and low-battery alerts.
Best for: Frequent mobile banking and e-commerce users who want phishing protection without upgrading.
Skip if: You need scheduled scanning. That’s a premium-only feature here.
Price: Free, with low-cost premium upgrade | Platform: Android
9. Trend Micro Mobile Security: Best for Social Media Protection
Trend Micro’s free tier scans apps before installation, not just after, which catches some threats other apps miss until it’s too late. It also includes a built-in Facebook privacy scanner that flags when your profile settings are exposing more personal data than you’d expect, plus scanning for dangerous URLs and insecure Wi-Fi connections.
Its AI-driven detection extends beyond basic viruses to ransomware and crypto-mining malware, and a hidden “snap” feature captures a photo of anyone attempting unauthorised access, similar to McAfee’s CaptureCam. A remote console lets you locate or wipe a missing device if needed.
Best for: Heavy social media users who want privacy exposure checks alongside malware protection.
Skip if: You don’t use Facebook; that specific feature won’t add value for you.
Price: Free, with premium version for more functionality | Platform: Android
10. Malwarebytes Security: Best Lightweight Privacy Scanner
Malwarebytes doesn’t make as many “best of” lists as the bigger consumer brands, but it remains a reliable, no-frills option for spotting adware and malware that other scanners sometimes miss, particularly in apps sideloaded outside the Play Store.
The free tier includes privacy audits and on-demand malware/adware detection and removal, but notably lacks real-time, continuous scanning; you’ll need to run scans manually rather than have the app watch in the background. The premium version adds real-time protection and phishing URL safety checks, with a 30-day trial to test it out.
Best for: A second-opinion scanner alongside your primary antivirus app, or users who prefer manual control over background scanning.
Skip if: You want continuous real-time protection without upgrading. This isn’t the app for that on the free tier.
Price: Free, with premium upgrade for real-time protection | Platform: Android
A Note on Norton: Why It’s Not in the Main List Anymore
Norton Mobile Security used to be a strong, genuinely free pick, and older “best free antivirus” lists (including earlier versions of this one) recommended it heavily. That’s changed: Norton no longer offers a real free tier for Android in 2026.
It’s available as a 14-day free trial, after which it requires a paid subscription (roughly $19.99/year standalone, or bundled into Norton 360 plans), backed by a 60-day money-back guarantee if you do decide to pay.
If you specifically want Norton’s protection, the trial is a reasonable way to test it, and its detection rates remain excellent in independent testing. But since this article is about free options, it no longer qualifies for the main list, and we didn’t want to repeat outdated advice.
Comparison: Free-Tier Feature Coverage
| Feature | Bitdefender | Avira | Kaspersky | AVG | Avast |
|---|---|---|---|---|---|
| Real-time scanning | Yes | Yes | No (manual only) | Yes | Yes |
| Anti-theft (remote lock/wipe) | Paid only | Yes | Yes | Yes | Limited |
| App locker | Paid only | Yes | Paid only | Paid only | Yes |
| VPN included | 200MB/day | Paid only | Paid only | Paid only | Limited |
| Ad-heavy free tier | No | No | No | Some | Yes |
Buying Guide: How to Choose a Free Android Antivirus
If you want the simplest, most hands-off option: Bitdefender’s Autopilot handles decisions automatically, so it’s the easiest to install and forget.
If you want the most complete free feature set: Avira gives you an app locker, breach monitoring, and privacy advisor without paying, more than most “free” competitors bundle in.
If anti-theft matters most (lost or stolen phone risk): Kaspersky or McAfee both offer strong remote lock/wipe/locate tools on the free tier.
If you do a lot of mobile banking or online shopping: ESET’s browser-integrated anti-phishing protection is one of the stronger free options for this specific use case.
If you’d rather avoid ad-heavy upsell prompts entirely: Sophos and Bitdefender are the cleanest free experiences on this list.
If you’re already using one Gen Digital product (Avast, AVG, Avira, or Norton): Consider picking a differently-owned engine (Bitdefender, Kaspersky, ESET, Sophos) for a genuinely independent second opinion, rather than assuming two Gen Digital apps give you two separate perspectives.
Common Mistakes to Avoid
- Assuming Google Play Protect alone is enough. It’s a solid baseline, but it consistently scores below dedicated antivirus apps in independent testing, particularly for phishing and zero-day threats.
- Relying on outdated “best free” lists that still recommend Norton as free. Check the current pricing page before installing, especially for apps with a history of moving features behind a paywall.
- Installing multiple full-featured antivirus apps at once. Running two real-time scanners simultaneously can conflict and drain your battery unnecessarily; use one primary app and, at most, a manual second-opinion scanner like Malwarebytes.
- Ignoring app permissions during setup. A security app requesting access to contacts, SMS, and call logs is normal for anti-theft features, but it’s worth understanding why each permission is requested rather than tapping through blindly.
Expert Tips for Better Android Security
- Enable Google Play Protect alongside your chosen third-party app; they don’t conflict, and Play Protect adds a baseline layer even when combined with a dedicated scanner.
- Avoid sideloading APKs from outside the Play Store when possible; this is where most Android malware infections actually originate, regardless of which antivirus app you’re running.
- Turn on automatic app updates for your antivirus app itself, not just your other apps, since malware definitions and detection engines improve with frequent updates.
- If you’re on a rooted device or frequently sideload apps, prioritise an app with strong real-time scanning (Bitdefender, Avira, or AVG) over one that only scans on-demand.
Final Thoughts
For most Android users in 2026, Bitdefender Mobile Security remains the safest default recommendation: strong lab scores, minimal system impact, and no aggressive upselling.
If you want a slightly richer free feature set and don’t mind a marginally heavier app, Avira is a close second. And if a “best free antivirus” list you’re reading still recommends Norton without a caveat, that’s a sign it hasn’t been updated recently. Always double-check the app’s current Play Store listing before installing.

Frequently Asked Questions
Google Play Protect is built into every Android device with the Play Store, but independent testing shows it scores lower on threat detection than dedicated antivirus apps. If you only install apps from the Play Store and avoid sideloading, Play Protect alone is often sufficient; if you sideload apps, use a rooted device, or want stronger phishing protection, a third-party app adds meaningful coverage.
Bitdefender Mobile Security is the strongest overall free pick based on current independent lab testing, with Avira close behind for offering a more complete free feature set.
No. As of 2026, Norton Mobile Security is only available as a 14-day free trial, followed by a paid subscription. It no longer offers a genuine ongoing free tier.
Open the Google Play Store app, tap the profile icon, go to Play Protect, and tap Scan. You can also use any third-party antivirus app from this list to run a manual or scheduled scan.
Yes. Google Play Protect is Android’s built-in malware scanning feature, accessible through the Play Store app, and it runs automatically in the background on most devices.
Effectively, yes. Avast acquired AVG in 2016, and both are now part of Gen Digital, the same parent company that owns Norton and Avira following a series of mergers.
Yes. Kaspersky ceased consumer operations in the United States in 2024 due to a US government restriction, but this doesn’t affect its availability, functionality, or support for users in India, where it continues to operate as normal.
It’s generally not recommended to run two real-time scanners simultaneously, as they can conflict and drain your battery. Using one primary antivirus app alongside occasional manual scans from a second app (like Malwarebytes) is a safer approach.
Lightweight apps like Bitdefender and Avira, which rely heavily on cloud-based scanning, have minimal impact on performance. Heavier, feature-packed free apps can have a more noticeable effect, particularly during a full system scan.
Real-time scanning checks apps and files continuously as they’re installed or accessed, catching threats immediately. Manual scanning only checks your device when you actively start a scan, which means a threat could sit undetected between scans.
Some do, with limits. Bitdefender’s free tier includes 200MB of VPN data per day, while most other apps on this list reserve VPN access for paid upgrades.
Yes, for most users. Apps like Bitdefender, Avira, Kaspersky, and Sophos post excellent independent lab scores on their free tiers. Paid upgrades typically add convenience features like real-time anti-theft, ad removal, and unlimited VPN, rather than fundamentally better malware detection.
