In 2026, threats to Android smartphones have become more complex: from hidden cryptocurrency mining to phishing attacks via instant messengers. Even if you don't install suspicious APKs, viruses can sneak in through vulnerabilities in legitimate apps or infected ad networks. The choice of antivirus now depends not only on the level of protection, but also on how the app affects battery autonomysystem speed and data confidentiality.

We tested 15 antiviruses on devices with Android 12–15, evaluating them according to 7 criteria: detection of threats in real time, phishing blocking, performance impact, additional features (VPN, password manager) and privacy policy transparency. This guide contains only those solutions that have shown stable results in independent laboratories (AV-Test, AV-Comparatives) and have not had scandals with data leaks.

Spoiler: free antiviruses now they are almost as good as paid ones in basic protection, but their main problem is aggressive advertising and collection of telemetry. But paid versions (for example, Bitdefender Mobile Security or Kaspersky Premium) offer unique features such as protection against surveillance through the camera or blocking unwanted calls. Below we will look at which solution is suitable for whom.

1. Is antivirus needed on Android in 2026? Google claims that built-in protection is reliable enough for most users. Is this true in practice?

Google says built-in security Google Play Protect reliable enough for most users. Is this true in practice?

According to data, AV-Test, Play Protect blocks about 85–90% of known threats, but allows many new viruses, especially those distributed through third-party sources (APK). In addition, it does not protect against:

  • 🔗 Phishing links in SMS, Telegram or email (even if they lead to seemingly legitimate sites).
  • 📱 Spyware modules in popular applications (for example, some Chinese launchers or games collect location data).
  • 💰 Mobile fraud (fake bank notifications, SMS asking to transfer money).
  • 🔋 Hidden miningwhich drains the battery and heats up the processor.

Another nuance: Play Protect scans applications only during installation, but does not track their behavior in real time. If the virus is activated a week after installation, the system will not notice it. Therefore, you need an antivirus if you:

  • 📥 Install APK from third-party sources (even from trusted sites like APKMirror).
  • 💳 Use mobile banking or cryptocurrency wallets.
  • 👨‍💻 Store confidential documents (passport scans, contracts) on your phone.
  • 🌍 Do you often connect to public Wi-Fi (in cafes, airports).
📊 Do you use antivirus on Android?
Yes, paid
Yes, free
No, Play Protect is enough
I don’t know what I have installed
⚠️ Attention: If you use Android 15 with the function Private Space (isolated space for applications), some antiviruses may conflict with it. Before installing, check compatibility on the developer's website.

2. TOP 5 antiviruses for Android in 2026: comparison table

We have selected the best solutions based on the ratio of protection, functionality and impact on performance. support Android 12–15 and have a Russian-language interface.

Antivirus Threat detection (%) Impact on the battery Additional functions Price. (year)
Bitdefender Mobile Security 99.8% Low VPN (200 MB/day), surveillance protection, call blocking 1 200 ₽
Kaspersky Premium 99.5% Medium Password manager, payment protection, data leak checking 1 500 ₽
Norton 360 Deluxe 99.2% High VPN without limits, dark web monitoring, backup 2 100 ₽
Avast One 98.7% Low Memory optimizer, tracker blocking, Wi-Fi check Free (premium - 900 ₽)
Malwarebytes 97.5% Minimal Real-time scanning, adware removal Free (premium - 600 ₽)

Important: Norton 360 Deluxe showed the highest battery consumption in tests - up to 12% for 8 hours of active use. If autonomy is critical for you, choose Bitdefender or Malwarebytes.

All of the listed antiviruses were certified AV-Test in the first quarter of 2026. However, their effectiveness depends on the regularity of virus database updates. data-i="99">updates signatures every 2 hours, and Avast updates signatures every 2 hours, and Malwarebytes - once a day.

💡

Before purchasing a paid version, check whether the antivirus has a trial period (usually 7-30 days) This way you can evaluate the impact on the performance of your device.

3. antiviruses: what to choose?

The main difference between free versions is the lack of real-time protection. They scan files only at the user’s request, which reduces their effectiveness against new threats. For example, if you download an infected APK, the free antivirus will not block it until you manually run the scan.

What do paid versions provide (using an example Kaspersky Premium):

  • 🛡️ Real-time protection — scans all downloaded files and installed applications.
  • 🔒 Blocking phishing sites in the browser and instant messengers (including Telegram and WhatsApp).
  • 📱 Anti-spyware functions —alerts about attempts access to the camera, microphone or geolocation.
  • 💳 Payment protection —a secure browser for online shopping.

But there are also pitfalls:

  • 📉 System load: some antiviruses (for example Norton) can slow down old smartphones (with weaker processors Snapdragon 6xx).
  • 📊 Data collection: even paid antiviruses (except Bitdefender i Malwarebytes) transmit anonymized telemetry. You can disable this in the settings.
  • 🔄 Auto-renewal of subscription: many services automatically write off money after the term expires. Google Play after payment.

If your budget is limited, the best option is Malwarebytes (free version) + Google Play Protect. This combo closes 95% of threats with minimal impact on performance. For maximum protection, it is better to choose Bitdefender Mobile Security (1,200 ₽/year).

How to disable auto-renewal of a subscription?

Go to Google Play → Profile → Payments and subscriptions → Manage subscriptions. Find the antivirus in the list and disable auto-renewal.

4. Which antivirus is better for weak smartphones?

On devices with 2–3 GB of RAM level processors, many antiviruses cause lags and overheating. We tested 5 solutions for Snapdragon 4xx/Helio P22 Many antiviruses cause lags and overheating. We tested 5 solutions on Redmi 9A (2020) and Samsung Galaxy A12:

Antivirus System slowdown Battery drain in 6 hours Recommendation
Malwarebytes No 3% ✅ Best choice
Avast One (free) Slight lags 5% 🟡 Acceptable
Bitdefender Noticeable lags 8% ❌ Not recommended
Kaspersky Strong lags 10% ❌ Not recommended

Conclusion: For weak smartphones only suitable Malwarebytes (free version) or Avast One with background scanning disabled. Paid antiviruses on such devices do more harm than good.

If you need a minimalistic antivirus without unnecessary functions, try Sophos Intercept XIt weighs only 15 MB and has no background processes, but updates the virus database once every 2 days (versus 2 hours for competitors).

5. How to properly install and configure an antivirus?

Even the most reliable antivirus is useless if configured incorrectly. Follow this algorithm:

  1. Download APK only from official sources:
    • 📱 Google Play (the safest option).
    • 🌐 Official website of the developer (for example, bitdefender.com).
    ⚠️ Attention: Do not install antiviruses from third-party stores (like APKPure or Aptoide) In 2026, several cases were recorded when miners were introduced into such assemblies.
  2. Provide the necessary permissions:
    • 📁 Access to files (for scanning).
    • 🔍 Overlay permission (to block phishing).
    • 📱 Device administrator (only if required by an antivirus to protect against theft).

Do not give access to SMS, Call log or Contacts — this is not necessary for basic protection.

  • Set up scanning: 
    Open antivirus → Settings → Scanning

    Set:
    

    - Scanning depth: "High"
    

    - Frequency: "Daily" (or "When connected to Wi-Fi")
    

    - Exceptions: add folders with personal files (photos, video)

  • Activate key modules:
    • 🛡️ Real-time protection (if available in your version).
    • 🌐 Blocking dangerous sites.
    • 🔄 Automatic update of virus databases.

      • After installation, run a full system scan. If the antivirus finds threats in system files (for example, in /system/app), do not delete them manually - this may cause Android to crash. Instead:

      1. Make a backup copy of your data.
      2. Update the firmware to the latest version. (vulnerabilities are often fixed in security patches).
      3. If the problem persists, contact antivirus support with scan logs.
    💡

    Never install two antiviruses at the same time! They will conflict, which will lead to reduced performance and false positives.

    6. Myths about antiviruses on Android, which include: You shouldn’t believe

    The Internet is full of advice that is not only useless, but also harmful. Let’s look at the most popular misconceptions:

    Myth 1: “An antivirus drains the battery by 50%”

    Reality: Modern antiviruses (for example, Bitdefender) consume no more 2–5% charge per day during standard use. The main battery hogs are background processes of social networks and instant messengers, not protection.

    Myth 2: “It is enough to scan your phone once a month”

    Reality: Viruses can be activated at any time. For example, a Trojan (distributed in 2026) steals bank card data immediately after installing an infected APK. If you scan your phone once a month, you risk losing money. Anubis (distributed in 2026) steals bank card data immediately after installing an infected APK. If you scan your phone once a month, you risk losing money.

    Myth 3: “Paid antiviruses are a scam.”

    Reality: Free versions really cover basic threats, but paid ones offer unique features:

    • 🔐 Protection against surveillance via camera/microphone (relevant for spying attacks).
    • 💳 Secure browser for payments (encrypts traffic even on HTTP sites).
    • 📧 Monitoring data leaks (notifies you if your email or password has appeared on the darknet).

    Myth 4: "Antivirus slows down the phone"

    Reality: Slowdown occurs only on weak devices (see section 4) or if the antivirus is not configured correctly. For example, constant scanning of thousands of files really slows down the system. Solution: exclude folders with music and videos from scanning. SD cards with thousands of files it really slows down the system. Solution: exclude music and video folders from scanning.

    Myth 5: “You can do without an antivirus, if you do not download pirated content"

    Reality: In 2026 30% of infections. occurs through legitimate applications from Google Play. For example, in March 2026, viruses were discovered in:

    • 📺 Applications for watching IP-TV (built-in mining).
    • 🎮 Mods for GTA San Andreas and Minecraft.
    • 📊 Financial trackers (theft of bank card data).

    7. Alternative ways to protect Android without an antivirus

    If you do not want to install an antivirus, use these measures:

    1. Android security settings

    • 🔒 Disable installation from unknown sources: Settings → Security → Unknown sources.
    • 🔄 Enable monthly security updates: Settings → System → System update.
    • 📱 Use Google Play Protect: check applications before installation.

    2. Safe behavior

    • 🌐 Do not follow links from SMS/messengers (even if they are from the “bank”).
    • 📎 Do not connect your phone to public charging (risk juice jacking - data theft via USB).
    • 🔑 Use password manager (for example, Bitwarden) to generate unique passwords.

    3. Additional tools

    • 🛡️ NetGuard (network traffic blocker) — limits application access to the Internet.
    • 🔍 Bouncer — temporarily grants permissions to applications (for example, access to geolocation for only 5 minutes).
    • 📡 1.1.1.1 (Cloudflare) — DNS with blocking of dangerous domains.

    These measures will reduce risks by 70–80%, but will not replace a full-fledged antivirus, if you actively use mobile banking or download APK.

    💡

    To scan suspicious files without installing an antivirus, use the online service VirusTotal. Download the APK there before installation.

    FAQ: Frequently asked questions about antiviruses on Android

    🔹 You can Is it possible to use an antivirus for Windows on Android through an emulator?

    No, this is not only useless, but also dangerous. Antiviruses for Windows (like Kaspersky Internet Security) do not recognize mobile threats. In addition, emulators (for example, Wine or BlueStacks) may themselves contain. vulnerabilities that hackers use to attack the host system.

    🔹 Which antivirus is better for a child (parental control)? summary>

    For children under 12 years old, we recommend Kaspersky Safe Kids or Norton FamilyThey allow:

    • Block access to dangerous sites and applications.
    • Limit the time you use your smartphone.
    • Track the child’s location (with his consent).

      • Important: Discuss cybersecurity rules with your child - no antivirus can replace conscious behavior.

    🔹 Why does an antivirus find viruses in system files?

    This could be:

    1. False positive (especially if you have custom firmware).
    2. Pre-installed software from the manufacturer (for example, Xiaomi or Samsung sometimes they add advertising modules that antiviruses mistakenly identify as a threat).
    3. Real virus in the firmware (rare, but happens with little-known brands).

    What to do: check the detected file through VirusTotal and contact antivirus support.

    🔹 How to remove an antivirus if it is not removed through the settings?

    Some antiviruses (for example, 360 Security) set themselves as device administrators. To remove them:

    1. Go to Settings → Security → Device Administrators.
    2. Uncheck the box next to the antivirus.
    3. Now you can remove it in the standard way.

    If this does not help, use ADB: 

    adb uninstall com.package name

    You can find out the name of the package through Settings → Applications → [Antivirus] → Information.

    🔹 Is it worth buying an antivirus with a lifetime license?

    No, it’s risky. Most antiviruses with “lifetime” licenses:

    • Stop updating virus databases after 2-3 years.
    • They may be fake (sold on dubious sites).
    • They do not support new versions of Android.

    It is better to choose an annual subscription with auto-renewal - this way you will always use the current version.
