Best Antivirus for Android: 4 Apps Compared

Android phones hold passwords, financial apps, private messages, photographs, work files, and access to important online accounts. Protecting that information matters, but a separate antivirus app is not essential for every Android user.

Most supported Android devices already include Google Play Protect, which checks apps before and after installation, scans software installed outside Google Play, warns about potentially harmful apps, and may disable or remove detected threats.

A third-party security app may still be worthwhile if you sideload applications, frequently open links from messages, use third-party app stores, or want additional phishing, scam, VPN, identity-monitoring, and privacy tools.

This guide compares four established options:

Bitdefender Mobile Security
Norton 360 for Mobile
Avast One
McAfee Mobile Security

Quick Comparison

Security option	Editorial recommendation	Cost model	May 2026 AV-TEST score
Bitdefender Mobile Security	Best focused protection	Paid with trial	18/18
Norton 360 for Mobile	Best for web and scam protection	Paid	18/18
Avast One	Best free option	Free with paid upgrades	18/18
McAfee Mobile Security	Best all-in-one bundle	Paid plans	18/18
Google Play Protect	Built-in baseline	Included with Android	16.5/18

AV-TEST evaluated 12 Android security products in May 2026. Avast, Bitdefender, McAfee, and Norton each received six points for protection, performance, and usability. Google Play Protect received 5.5 for protection, six for performance, and five for usability.

A six-month AV-TEST endurance study published on July 14, 2026, broadly reinforced those results. Avast, Bitdefender, and Norton detected all of the nearly 17,500 malicious applications used. McAfee missed one real-time sample, recording 99.9% in that segment, but still earned the full protection score.

The “best for” labels in this article are editorial recommendations based on laboratory results, product features, cost models, and intended users. They are not award titles issued by AV-TEST or AV-Comparatives.

Does Android Need a Separate Antivirus App?

Google Play Protect may be enough when you:

Install apps only from Google Play
Keep Android and apps updated
Avoid unknown APK files
Review app permissions carefully
Use a strong screen lock
Recognize suspicious messages and links
Keep important data backed up

Additional protection may be useful when you:

Sideload applications
Use third-party app stores
Test unfamiliar software
Frequently receive scam texts or emails
Want active phishing-site blocking
Store sensitive business or financial information
Need VPN or identity-monitoring tools
Manage several family devices

AV-Comparatives advises Android users to keep the operating system patched, examine permissions, avoid risky links and downloads, maintain backups, and treat third-party security apps as supplements to Android’s built-in defenses.

What Google Play Protect Provides

Play Protect is enabled by default on supported Android devices using Google Mobile Services.

It can:

Check Google Play apps before installation
Scan installed apps periodically
Examine software installed from other sources
Warn about harmful or deceptive applications
Disable or remove certain threats
Request additional analysis of unfamiliar sideloaded apps

Google recommends keeping Play Protect enabled, especially when installing applications from outside Google Play.

Independent testing shows why some users may still want another layer. In AV-Comparatives’ May 2026 test, Bitdefender detected 100% of 3,156 malicious applications, Avast and Norton detected 99.6%, and Google Play Protect detected 98.9%. The laboratory recorded two false positives for Bitdefender, Avast, and Norton, compared with eight for Play Protect. All tested products had only a minor effect on battery life.

Play Protect remains valuable automatic protection, but commercial suites can add more extensive scam screening, web protection, application auditing, VPN access, and identity tools.

How the Apps Were Evaluated

The recommendations considered:

AV-TEST’s May 2026 Android evaluation
AV-TEST’s six-month endurance study
AV-Comparatives’ May 2026 mobile review
Malware detection and false positives
Performance and battery impact
Phishing and scam protection
Privacy and identity features
Ease of use
Free-versus-paid value
Current Android availability

All four recommendations appeared in AV-TEST’s May 2026 evaluation and endurance study. Bitdefender, Avast, and Norton were also included in AV-Comparatives’ 2026 Mobile Security Review. McAfee was not part of that AV-Comparatives review, so its independent assessment here relies on AV-TEST alongside McAfee’s official product documentation.

1. Bitdefender Mobile Security

Best for focused, well-rounded paid protection

Bitdefender Mobile Security combines malware scanning with web protection, scam detection, App Lock, breach monitoring, anti-theft controls, and a limited VPN.

Its included VPN provides up to 200 MB of encrypted traffic per day. Unlimited traffic and manual location selection require a separate Premium VPN subscription.

Bitdefender earned 18 out of 18 from AV-TEST in May 2026. It also detected 100% of AV-Comparatives’ malware samples with two false positives and recorded perfect detection throughout AV-TEST’s six-month endurance study.

Main advantage: Strong malware results combined with a focused, easy-to-understand feature set.

Main limitation: It is primarily a paid product, and the included VPN allowance is too small for regular streaming or heavy browsing.

2. Norton 360 for Mobile

Best for malicious-site, application, and scam protection

Norton 360 for Mobile includes device security, Web Protection, Wi-Fi alerts, App Advisor, VPN access, Dark Web Monitoring, and AI-assisted scam protection.

On Android, App Advisor checks installed apps, updates, and Google Play listings for malware, ransomware, adware, and privacy risks. Norton distinguishes this product from the simpler Norton Mobile Security plan, which does not include the same VPN and Dark Web Monitoring package.

Norton 360 received 18 out of 18 from AV-TEST in May 2026 and detected every malicious app in the six-month endurance test. In AV-Comparatives’ May review, the shared Avast–AVG–Norton engine group recorded 99.6% protection with two false positives.

Main advantage: Broad protection against unsafe applications, websites, networks, and modern scams.

Main limitation: Norton’s overlapping plans can be confusing. Confirm that the subscription is Norton 360 for Mobile rather than the more limited Norton Mobile Security product.

3. Avast One

Best free option

Avast One offers a free tier with malware protection and additional security, privacy, and scam-related tools.

AV-Comparatives describes Avast One Free as an advertising-supported app with anti-malware protection, safe browsing, application auditing, scam protection, Wi-Fi checks, breach alerts, and a photo vault. Paid upgrades unlock additional features.

Avast is gradually replacing its older Avast Mobile Security and previous Avast One applications with a new unified Avast One app. Independent laboratories may therefore display names such as “Avast Antivirus & Security” or “Avast One Free,” even though users are being migrated toward the new Avast One experience.

Avast earned the maximum 18 points from AV-TEST in May 2026 and achieved perfect detection in the six-month endurance test. AV-Comparatives measured 99.6% protection with two false positives for the Avast engine group.

Main advantage: Meaningful malware, web, scam, and Wi-Fi protection without requiring an immediate paid subscription.

Main limitation: The free version contains advertising and upgrade prompts. Storage-cleaning and optimization tools should not be mistaken for core security protection.

4. McAfee Mobile Security

Best for antivirus, VPN, scams, and identity tools in one plan

McAfee Mobile Security combines Android antivirus with scam detection, safe browsing, VPN access, identity monitoring, and breach alerts. Available features depend on the selected subscription.

McAfee’s Scam Detector is designed to analyze suspicious texts, emails, links, and other content. Its mobile plans can also include an unlimited VPN and monitoring for exposed personal information.

McAfee received 18 out of 18 in AV-TEST’s May 2026 evaluation. In the six-month endurance test, it detected 99.9% of the newest malware samples and 100% of the established samples, while still earning the full six protection points.

Main advantage: A broad package for users who want security, privacy, scams, identity monitoring, and multi-device coverage together.

Main limitation: It may be excessive or expensive for someone who only wants a basic malware scanner.

Free or Paid: Which Should You Choose?

Use Google Play Protect alone when your exposure is low and you consistently follow safe app and account practices.

Choose Avast One when you want free third-party malware, web, Wi-Fi, and scam protection.

Consider paying for Bitdefender when you want focused protection with App Lock and breach monitoring.

Choose Norton 360 for Mobile when malicious websites, suspicious apps, scams, and VPN privacy are the main concerns.

Choose McAfee when you want mobile antivirus within a larger identity, VPN, and family-security package.

A paid plan is worthwhile only when its additional features solve a real need. A long feature list does not automatically make an application safer.

Android Security Habits That Matter More

No security app can make careless behavior risk-free.

Keep software updated

Install Android, Google Play system, browser, and application updates promptly. Updates often correct vulnerabilities that antivirus alone cannot resolve.

Protect the lock screen

Use a strong PIN, password, or secure biometric method. The FTC recommends at least a six-digit passcode and automatic screen locking.

Review permissions

Be suspicious when a basic app requests access to messages, contacts, accessibility controls, the microphone, precise location, or device administration without a clear reason.

Use multifactor authentication

Enable it for email, banking, cloud storage, social media, and other important accounts.

Download carefully

Prefer Google Play, verify the publisher, review the Data Safety section, and avoid unknown APK files. Play Store screening reduces risk but cannot guarantee that every app or later update will remain harmless.

Enable Find Hub and backups

Google’s built-in device-location service can help locate, secure, or erase supported devices. Keep current backups so theft, damage, or malware does not become permanent data loss.

How to Recognize a Fake Security App

Treat these signs as warnings:

An unknown publisher with no credible history
Constant alerts claiming the phone is severely infected
Immediate pressure to purchase an expensive subscription
Requests for unrelated permissions
Accessibility or administrator access without a clear reason
Promises of complete protection or dramatic speed improvements
More emphasis on cleaning memory than preventing threats
No independent testing history
Copied branding, spelling errors, or no privacy policy

AV-Comparatives notes that rogue antivirus apps may provide inadequate security, making independent testing and certification important.

Avoid installing multiple third-party real-time security suites. Leave Google Play Protect enabled alongside the single reputable security product you choose.

How to Remove Suspected Malware

Unusual battery drain alone does not prove that a phone is infected. Repeated redirects, unknown apps, unexplained administrator access, intrusive pop-ups, or suspicious account activity deserve closer investigation.

Remove unfamiliar recent apps. Start with anything installed immediately before the problem appeared.
Review powerful permissions. Check accessibility, device administrator, VPN, notification access, and permission to install unknown apps.
Run Play Protect and one reputable scan. Do not install several competing antivirus suites.
Update and secure your accounts. Install available updates, then change affected passwords from a trusted device and enable multifactor authentication.
Reset when serious symptoms remain. Back up essential personal files and perform a factory reset when malicious administration or persistent problems cannot be removed.

The FTC recommends using current security software, scanning suspected devices, avoiding sensitive account activity until the issue is resolved, and changing compromised passwords.

Frequently Asked Questions

Does Android have built-in antivirus?

Yes. Google Play Protect scans applications, checks new installations, warns about potentially harmful software, and may disable or remove detected threats.

Is Google Play Protect enough?

It can be enough for careful users who install trusted apps, keep Android updated, and avoid suspicious links. A third-party product can add stronger malware results and broader scam, web, VPN, or identity features.

What is the best free antivirus for Android?

Avast One is the strongest free choice among the four options compared here. It performed well in current independent testing, although the free version includes advertising and upgrade prompts.

Will antivirus slow down my phone?

A poorly designed application may affect performance. However, AV-Comparatives found that all products in its May 2026 Android review had only a minor influence on battery life.

Can Google Play apps contain malware?

Google screens applications and Play Protect continues scanning after installation, but no store can eliminate every risk. Check the publisher, permissions, update history, and security warnings before installing.

Should I use two antivirus apps?

Avoid using two third-party real-time security suites. Keep Google Play Protect enabled and pair it with no more than one reputable additional product.

Final Recommendation

Most Android users should begin with the protections they already have:

Keep Google Play Protect enabled.
Install updates promptly.
Use a strong screen lock.
Review app permissions.
Avoid unknown APK files.
Secure important accounts with multifactor authentication.
Maintain backups.

Choose Bitdefender Mobile Security for focused paid protection.

Choose Norton 360 for Mobile for strong application, web, VPN, and scam tools.

Choose Avast One for capable free protection.

Choose McAfee Mobile Security when you want antivirus within a broader VPN, identity, and family-security package.

Antivirus is one useful layer. Safe applications, current software, strong accounts, and careful decisions remain the foundation of Android security.
