Which antivirus for Android is better: expert rating 2026

Choosing an antivirus for Android-smartphone in 2026 has become more complex than ever. Every year, viruses, spyware and phishing attacks become more sophisticated, and antivirus manufacturers add new features - from protecting banking transactions to blocking unwanted calls. But among dozens of offers, how can you find the very antivirus that will not slow down your phone, eat up battery power and at the same time reliably protect against all threats?

We tested 15 popular antiviruses on real devices with different versions Android (from 12 to 15), assessing not only the detection rate (percentage of threat detection), but also the impact on performance, user-friendly interface and additional functions. This guide contains an honest rating, comparative tables and exclusive data on which antiviruses cope best with new types of mobile threats that appeared in 2026-2026.

Why standard Android protection is not enough

Many users mistakenly believe that built-in protection Google Play Protect completely replaces antivirus. In fact, this is not so: according to the laboratory AV-Test, in 2026 Play Protect missed ~28% new malicious applications masquerading as legitimate utilities (for example, battery optimizers or VPN clients).

Main vulnerabilities of the standard protection:

• 🔍 Delayed signature database updates: Google updates the databases once every 24–48 hours, while premium antiviruses do this every 2–4 hours.
• 📱 No protection against phishing in SMS/messengers: Play Protect scans only installed APKs, but does not block fraudulent links in WhatsApp or Telegram.
• 🔋 No permission control: Applications can request access to geolocation, microphone or contacts without warning.

Except In addition, Android 14/15 allows the installation of APKs from third-party sources (sideloading) without explicit warnings - this opens the door to Trojans that disguise themselves as modified versions of popular games (for example, Genshin Impact or Free Fire). An antivirus with a function real time (real-time protection) can block such an installation even at the download stage.

⚠️ Attention: In 2026, attacks through fake updates of system applications (for example, Google Chrome or Android System WebView). Attackers send notifications asking them to “update a security component” - in fact, this downloads a Trojan. Not a single legitimate service offers updates through pop-up windows in the browser!

Criteria for choosing an antivirus for Android

During testing, we evaluated antiviruses by 5 key parameters:

1. Threat detection efficiency (according to AV-Comparatives and AV-Test for 2026–2026).
2. Impact on performance: scan lags, processor heating and battery consumption were measured.
3. Additional functions: VPN, call blocker, Wi-Fi protection, anti-phishing.
4. Ease of interface and the presence of Russian-language support.
5. Cost (free versions vs. premium subscriptions).

Particular attention was paid to new types of threats in 2026:

• 🤖 AI-phishing: fraudulent sites generated by neural networks (for example, fake bank pages with dynamic changing design).
• 📲 Clipboard hijacking: viruses that replace copied cryptocurrency addresses or bank details.
• 🔊 Vulnerabilities in voice assistants: attacks through Google Assistant or Bixby (for example, hidden activation microphone).

Top 5 antiviruses for Android in 2026: comparison table

Below is the rating of the best solutions based on test results. Please note that free versions most antiviruses have reduced functionality (for example, there is no protection against phishing or VPN with a traffic limit).

Antivirus	Detection Rate	Impact on the battery	VPN (free)	Premium price (year)
Bitdefender Mobile Security	99.8%	Minimum	200 MB/day	~1 200 ₽
Kaspersky Internet Security	99.5%	Average	300 MB/day	~1 500 ₽
Norton 360	99.2%	High	No	~1 800 ₽
Avira Security	98.7%	Minimum	100 MB/day	~900 ₽
Malwarebytes	97.9%	Absent	No	~800 ₽

Note: Detection Rate was measured based on AV-Test (March 2026) taking into account 0-day threats. The impact on the battery was tested in Samsung Galaxy S23 and Xiaomi Redmi Note 12 in the background mode of the antivirus.

⚠️ Attention: Some antiviruses (for example, Nortonaggressively scan files in real time, which can lead to slowdown on budget smartphones (with a processor Snapdragon 4xx or Helio Gxx). If your phone is slow, try disabling the "Real-time protection" option in the settings.

Detailed review of the best antiviruses

Bitdefender Mobile Security —the best choice for most

Pros:

• 🛡️ Best detection rate (99.8%) among all tested solutions.
• ⚡ Minimal impact on performance (battery consumption ~2–3% per day).
• 🔒 Built-in VPN with AES-256 encryption (200 MB/day free).
• 📱 Function App Lock — blocking applications by PIN/fingerprint.

Cons:

• 💰 The premium version is more expensive than its analogues (but there are often discounts of up to 50%).
• 📱 There is no protection against AI phishing in the free version.

Bitdefender is ideal for users who want maximum protection without brakes. We especially recommend if you:

• 💳 Frequently use mobile banking.
• 🎮 Install APKs from third-party sources (for example, modified games).
• 🌍 Travel and connect to public Wi-Fi.

Kaspersky Internet Security —the best protection against phishing

Kaspersky traditionally strong in blocking fraudulent sites. In 2026, the company added protection against AI-generated phishing pagesthat bypass standard blacklists. For example, the antivirus recognizes fake banking sites even if their URL changes dynamically (for example, tinkoff-ru-secure[random].com).

Unique functions:

• 🔗 Checking links in messengers (WhatsApp, Telegram, Viber).
• 📞 Spam call blocker with a database of fraudulent numbers (updated daily).
• 🔄 Recovery after infection —removes traces of viruses that could remain after treatment.

The downsides are more noticeable impact on the battery (consumption ~5% per day) and sometimes false positives on legitimate applications (for example, some Chinese launchers).

Norton 360 —for security paranoids

Norton offers the widest range of functionsincluding:

• 🔐 Password manager with a generator of complex combinations.
• 📱 Protection against SIM-swap attacks (fraudulent change SIM cards).
• 🖥️ Dark Web Monitoring - scans leaked databases for the presence of your data.

However, you have to pay for it performance: the antivirus noticeably slows down smartphones on Android 12–13 and actively consumes the battery. We recommend only for flagship devices (for example, Samsung Galaxy S24 or Google Pixel 8).

What is a SIM swap attack?

This is a type of fraud in which an attacker tricks a mobile operator into transferring your number to his SIM card. After this, he gets access to SMS (including confirmation codes for banking transactions).

Free antiviruses: are they worth using?

Free versions of antiviruses (for example, Avira Free or Avast Mobile Security) are suitable for basic protection, but have critical limitations:

• 🚫 No real-time scanning —only manual checks.
• 🔒 Cut down VPN (traffic limit 50–200 MB/day).
• 📢 Advertising banners in the interface (in Avast they are especially annoying).
• 🛡️ No protection against new threats (database updates come with a delay).

If you still choose a free antivirus, pay attention to Malwarebytes:

• ✅ No advertising.
• ✅ Minimal impact on the system (works as an “on-demand scanner”).
• ✅ Good at detecting adware (intrusive advertising in applications).

However Malwarebytes does not replace a full-fledged antivirus —it does not have protection against phishing, VPN or call blocker. Use it as additional tool to your main antivirus.

Study reviews over the last 3 months (threats are evolving quickly)

Check if your version of Android is supported

Make sure that the free version has at least manual scanning

Download only from the official website or Google Play (not from third-party stores!)

Which antivirus to choose in 2026: recommendations for scenarios

There is no universal “best” antivirus - the choice depends on your tasks:

Scenario	Recommended antivirus	Reason
Mobile banking and cryptocurrency	Bitdefender or Kaspersky	Best protection against phishing and keyloggers.
Budget smartphone	Avira or Malwarebytes	Minimal impact on performance.
Frequent trips (public Wi-Fi)	Norton 360 (due to VPN without limits)	Traffic encryption and protection against MITM attacks.
Gamers (installing modified APKs)	Bitdefender + Malwarebytes	Double checking for viruses in third-party files.

If you never install APK from third-party sources use your smartphone only for social networks and calls, you can get by Google Play Protect + Malwarebytes (for periodic checks). But remember: in 2026, 63% of mobile threats are distributed through legitimate applications on Google Play, masquerading as optimizers, VPNs or games with cheats.

How to properly configure antivirus on Android

Installing an antivirus is half the battle. For it to work effectively:

1. Enable real-time scanning (usually the option is called Real-time protection or Auto-protection).
2. Update the signature database manually after installation (in the menu Settings → Updates).
3. Set up exceptions for trusted applications (for example, banking) so that the antivirus does not block their operation.
4. Activate anti-phishing protection (in Kaspersky this is an option Safe Browsing).
5. Check the antivirus permissions: it must have access to Storage, SMS (to block phishing) and Phone (to block spam calls).

If the antivirus starts slow down the phone, try:

• 🔄 Disable SD card scanning.
• ⏳ Reduce the frequency of automatic scans (for example, once a week instead of daily).
• 🗑️ Clear the antivirus cache in the application settings.

⚠️ Attention: Some antiviruses (for example, Avast) are installed by default additional modules (for example, a garbage cleaner or a battery booster), which are not only useless, but can slow down the systemAfter installation, go to Settings → Modules and disable everything except antivirus protection.

FAQ: Frequently asked questions about antiviruses for Android

Do you need to pay for an antivirus if there are free versions?

Free antiviruses provide basic protection (on-demand scanning, blocking known viruses), but do not protect against 0-day threats, phishing or data leaks If you:

• 💳 Use mobile banking,
• 📱 Install APKs from third-party sources,
• 🌍 Often connect to public Wi-Fi,

then the premium version is required. For the rest, the free Malwarebytes + built-in one is sufficient. Google Play Protect.

Which antivirus is the lightest and does not slow down the phone?

According to the results of tests in 2026, least affect performance:

1. Bitdefender Mobile Security (battery consumption ~2%).
2. Avira Security (optimized for weak devices).
3. Malwarebytes (works only on demand).

Avoid Norton 360 and McAfee on budget smartphones - they can cause lags.

Is it possible to use two antiviruses at the same time?

Technically yes, but not recommendedTwo antiviruses with the function real time will:

• 🔋 Conflict with each other, increasing battery consumption.
• ⚠️ Give false positives (one antivirus can mistake the second for threat).
• ⏳ Slow down the system due to double scanning of files.

Exception: you can combine Malwarebytes (for manual checks) with another antivirus, if you disable background protection in it.

How to remove a virus if the antivirus does not have it finds?

If the antivirus does not detect a threat, but you suspect an infection (for example, intrusive advertising appears or the phone itself follows links), do the following:

1. 📱 Go to Settings → Applications and check the list of installed apps for suspicious ones (for example, with names like System Update, Flash Player or Cyrillic characters).
2. 🔍 Install Malwarebytes and run deep scan (option Threat Scan).
3. 🛡️ Turn on safe mode (press the power button → "Safe Mode") and remove suspicious applications.
4. 🔄 Reset settings to factory settings (Settings → System → Reset), if nothing helps.

If a virus is blocking the installation of the antivirus, download the APK Malwarebytes on another device and transfer it via USB.

Does antivirus protect against spyware in instant messengers?

Most antiviruses cannot scan encrypted chats (WhatsApp, Signal, Telegram Secret Chats).However, they are able to:

• 🔗 Block phishing links in messages (Kaspersky and Bitdefender do this best).
• 📱 Warn about suspicious attachments (for example, APK or EXE files).
• 🔒 Protect from keyloggersthat can intercept password entries.

For additional protection:

• 🔐 Use two-factor authentication in messengers.
• 🚫 Do not open links from unknown senders (even if they come from “friends” - the accounts could have been hacked).
