Has your smartphone started to slow down, show strange ads, or open applications spontaneously? Your device is likely infected with malware. In 2026, viruses for mobile devices have become more sophisticated: they disguise themselves as system processes, steal bank card data through phishing windows, and even use the phone to mine cryptocurrency in the background. At the same time, most users do not suspect an infection until the last minute, attributing the symptoms to “firmware glitches” or a “weak processor.” Android Has it started to slow down, show strange ads, or open applications spontaneously? Your device is likely infected with malware. In 2026, viruses for mobile devices have become more sophisticated: they disguise themselves as system processes, steal bank card data through phishing windows, and even use the phone to mine cryptocurrency in the background.

This article will help accurately diagnose the virus on your Androiddevice (including models Samsung Galaxy, Xiaomi Redmi, Google Pixel and others), determine its type and completely remove without data loss. We will analyze both automatic methods using antiviruses, and manual ones for experienced users. We will pay special attention new types of mobile threats in 2026that bypass standard protection measures.

Signs of infection: how to understand what’s on the phone virus

Malware on Android rarely reveals itself with bright pop-up windows with the words “Your phone is infected!” - it usually acts secretly. Here 12 key symptomsthat should alert you:

  • 🔋 Rapid battery drain (more than 20% per hour in standby mode) - the virus can work in the background, consuming resources.
  • 📱 Spontaneous actions: sending SMS, installing applications, opening a browser with unknown sites.
  • 💰 Unauthorized payments - write-offs of small amounts (50–300 rubles) from a bank card linked to Google Pay.
  • 📈 Sharp increase in traffic - viruses are often "drained" data to remote servers (check in Settings → SIM cards and mobile networks → Traffic usage).
  • 🔍 The appearance of unfamiliar applications in the menu or in the list of installed apps (for example, System Update, Flash Player, Cleaner Pro).
  • 📛 Advertising in unexpected places: banners on top of lock screens, in games without the Internet, in system notifications.

One of the most insidious signs is increasing body temperature no load Modern viruses (for example, Anubis or Cerberus) use the phone's processor for mining or distributed attacks (DDoS), which leads to overheating. If your Samsung Galaxy S23 or Xiaomi 14 heats up to 45–50°C in standby mode, this is a reason for a deep check.

⚠️ Attention: Some "symptoms" may be caused not by viruses, but by problems. firmware or battery wearFor example, rapid battery drain on phones older than 3 years is normal. Before treating viruses, rule out hardware faults.

Top 5 antiviruses for Android in 2026: which one to choose

Standard Google Play Protect (built-in protection Android) detects only ~60% of threats. For deep scanning, we need specialized antiviruses. tested 15 solutions and selected the best ones in terms of ratio efficiency/system load:

Antivirus Threat detection (%) Impact on performance Free version Features
Bitdefender Mobile Security 99.8% Minimum 14 days Phishing protection, VPN (200 MB/day), vulnerability scanner
Kaspersky Internet Security 99.5% Average Yes (with restrictions) Blocking fraudulent calls, checking links in messengers
Malwarebytes 98.7% Low Yes Specializes in adware and spyware, no background check
Norton 360 99.2% High 7 days Includes password manager and identity theft protection
Avira Antivirus 97.3% Low Yes Memory optimizer, check external drives

For most users, the optimal choice would be Bitdefender or Malwarebytes. The first is suitable for comprehensive protection (including banking transactions), the second is for a one-time deep scan. If you need maximum confidentiality, pay attention to Kaspersky - it blocks not only viruses, but also. surveillance via microphone/camera.

⚠️ Attention: Some antiviruses (for example, Cheetah Mobile or DU Antivirus) are themselves recognized as potentially dangerous. They often collect user data for targeted advertising. Before installing, check the reputation of the app. on VirusTotal or MetaCert.

Step-by-step guide: how to check your phone for viruses

Before removing the virus, you need accurately confirm its presence to determine the type of threat:

  1. Checking through safe mode

    Reboot the phone into Safe Mode (to do this, hold down the power button, then long tap select "Safe Mode") In this mode, only system applications work. If the symptoms (advertising, brakes) have disappeared, the virus is certain. yes.

  2. Analysis of installed applications

    Go to Settings → Applications → All applications and sort by installation date Pay attention to apps with names:

    • 📦 System Update, Android Update, Google Play Service Update (fake updates)
    • 🎮 Fortnite Mobile, PUBG Lite, Free Fire Hack (cheats for games with viruses)
    • 🔍 Clean Master, Speed Booster, Battery Saver Pro (fake optimizers)

  • Checking application rights

    Viruses often ask for suspicious permissions. Open Settings → Applications → Permissions and find apps with rights:

    • 📱 Device administrator (may block removal)
    • 🔄 Run at startup systems
    • 📡 Sending SMS or calls
    • 💳 Accessing payment data

      • If you find a suspicious application, do not remove it immediately - some viruses activate protection when trying to uninstall. First, revoke all permissions from it, then proceed to removal (more on this in the next section).

      💡

      Viruses are often disguised as system processes with names like com.android.system or android.process.media. to distinguish them from the real ones, compare the file size: system services rarely take up more than 50 MB, and viruses often take 100+ MB.

      How to remove a virus from Android: 4 working methods

      The removal method depends on the type of virus and access rightsthat it received. Let's look at the methods from the simplest to the most radical.

      Method 1: Removal via antivirus (for adware and Trojans)

      If the virus has not blocked the installation of new apps:

      1. Download Bitdefender or Malwarebytes from Google Play (not from third-party sites!).
      2. Run deep scan (not fast!).
      3. Remove all detected threats and restart the phone.

      If the antivirus does not find the virus, but the symptoms remain, proceed to the next method.

      Method 2: Manual removal through settings (for regular applications)

      For applications without administrator rights:

      1. Go to Settings → Applications.
      2. Find the suspicious application and tap "Delete".
      3. If the button is inactive, first revoke permission Device Administrator to Settings → Security → Device administrators.

      Method 3: Removal via ADB (for system viruses)

      If the virus is embedded in system files (often happens on phones with root access), it will help Android Debug Bridge: 

      adb shell

      pm list packages | grep "suspicious_name"
      

      pm uninstall -k --user 0 package name

      This method requires connecting the phone to the PC and turning on USB debugging mode (Settings → For developers → USB debugging).

      Method 4: Reset to factory settings (as a last resort)

      If all else fails:

      1. Create a backup copy of important data (photos, contacts) to a PC or cloud.
      2. Go to Settings → System → Reset settings.
      3. Select "Delete all data" and confirm.

      After the reset do not restore data from a backup copy - the virus may return. Install applications only from Google Play i. check their reviews.

      💡

      If the virus has blocked access to your phone settings, try removing it via recovery mode (Recovery Mode) To do this, turn off the phone, then press Power + Volume up and select Wipe data/factory reset.

      What to do if a virus has blocked your phone

      Some viruses (for example, Simplocker or LeakerLocker) block the phone screen, demanding a ransom. In this case:

      1. Reboot to safe mode

        Hold the power button for 10-15 seconds until the phone turns off. Then turn it on while holding down the button Volume down (on some models - Volume upIn safe mode, try removing the virus through). settings.

      2. Password reset via Google Find My Device

        If the screen is locked with a password that you did not set:

        1. Login to Google Find My Device from another device.
        2. Select your phone and click "Lock device."
        3. Set a new password (the virus block will be reset).

      3. Removal via TWRP (for advanced users)

        If custom recovery is installed on your phone (TWRP), you can manually delete virus files: 

        1. Boot into TWRP (press Power + Volume Up).

        2. Select Advanced → File Manager.
        

        3. Go to /data/app/ and delete folders with suspicious applications.

    ⚠️ Attention: If the virus requires payment for unlocking (for example, in bitcoins) - never payThis does not guarantee unblocking, but will only confirm the functionality of the scammers’ scheme. support Google or your bank to block transactions.
    What to do if a virus encrypts files?

    If a virus encrypts your files (extensions type .locked, .crypt), the chances of recovery without a backup are minimal. Some ransomware (for example, WannaLocker) use vulnerabilities in Android 8–10, which are already closed in new versions. Update the firmware and check if the manufacturer has released a decryption tool (for example, Avast sometimes publishes keys for popular viruses).

    How to protect Android from viruses in the future

    Prevention is always cheaper than cure. Here 7 rulesthat will reduce the risk of infection to a minimum:

    • 🔒 Disable installation from unknown sources (Settings → Security → Unknown sources). Even if you need to install an APK, first check it at VirusTotal.
    • 📱 Update the firmware — in new versions Android vulnerabilities are closed, that exploit viruses. Check for updates in Settings → System → Software update.
    • 🛡️ Use two-factor authentication for Google Account and banking applications This will protect you even if a virus steals yours. passwords.
    • 🔍 Check application permissions before installation. If the messenger asks for access to SMS or geolocation, this is suspicious.
    • 💳 Do not store card data in the browser. Viruses like BankBot steal saved passwords and cookies.
    • 📴 Avoid public Wi-Fi for banking transactions. Fraudsters intercept traffic through fake access points (for example, "Free Airport Wi-Fi").
    • 🧹 Clear the cache regularly (Settings → Storage → Cache data). Some viruses hide in temporary files.

    Pay special attention children's devices. Viruses are often spread through pirated games (Minecraft, Roblox, Brawl Stars), which children download from dubious sites. Configure Google Family Linkto control the installation of applications.

    Frequently asked questions about viruses on Android

    Can a virus damage the phone's hardware (processor, battery, screen)?

    No, viruses cannot physically break phone components. However, they can:

    • 🔋 Accelerate battery wear - constant load on the processor will shorten the battery life.
    • 🔥 Cause overheating - if the phone regularly heats up above 50°C, this can damage the chipset or screen (the appearance of "yellow spots" on OLED).
    • 📵 Disable the speakers - some viruses play loud sounds at maximum volume, which theoretically can damage the membrane.

    But after removing the virus and returning to normal temperature conditions, the risks are reduced to zero.

    Is it true that viruses can steal photos and correspondence?

    Yes, and this is one of the most common threats. Viruses of the family SpyNote or Pegasus can:

    • 📸 Take screenshots of the screen every time you open the messenger.
    • 🎤 Include the microphone for wiretapping (even when the phone is lying without affairs).
    • 📁 Copy photos and videos in the cloud storage of attackers.
    • 💬 Intercept SMS (including confirmation codes from the bank).

    To protect yourself, regularly check Settings → Applications → Permissions and revoke access to the microphone/camera from suspicious apps.

    Can you get a virus via Bluetooth or NFC?

    Theoretically yes, but in practice such cases are extremely rare. Modern viruses spread mainly through:

    • 📥 Downloaded APK files (85% of cases).
    • 🌐 Phishing sites (12%).
    • 📧 Attachments in letters/messengers (3%).

    For infection via Bluetooth or NFC you need to:

    1. File transfer is enabled on both devices.
    2. You manually accepted a malicious file (for example, .apk or .jar).
    3. You installed and launched this file yourself.

    Thus, the risk is minimal - just do not accept files from unknown devices.

    How to check your phone for viruses without an antivirus?

    If you do not trust antiviruses or cannot install them, use manual methods:

    1. Checking traffic: go to Settings → SIM cards and mobile networks → Traffic usage. If some application consumes gigabytes of data, this is suspicious.
    2. Battery analysis: in Settings → Device care → Battery see which apps are using up power in the background.
    3. Search for suspicious processes: install OS Monitor or Simple System Monitor from Google Play —they will show all running processes and their resource consumption.
    4. DNS check: viruses sometimes change DNS servers. Check them in Settings → Wi-Fi → [your network] → Advanced → IP settings. Normal DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
    What to do if the antivirus finds a virus, but cannot remove it?

    If the antivirus detects a threat, but writes “Unable to remove”, try:

    1. Boot into safe mode and repeat the removal.
    2. Revoke administrator rights virus (Settings → Security → Device administrators).
    3. Use another antivirus —some apps specialize in certain types of viruses. For example, Malwarebytes is better at removing adware, and Kaspersky trojans.
    4. Remove manually via ADB (see instructions in the "Method 3" section).
    5. Contact antivirus support —some companies (for example, Bitdefender) help with the removal of complex viruses for free.

    If all else fails, the only thing left is reset to factory settings settings.
