How to install virus protection on an Android phone: 7 proven methods

Viruses on Android smartphones are a real threat that can lead to theft of personal data, blocking of the device, or hidden installation of adware. According to reports Kaspersky for 2026, every fifth Android user has encountered malware masquerading as legitimate applications. At the same time, 63% of infections occurred due to careless actions of the owners themselves: downloading files from unverified sources, ignoring system updates or using vulnerable firmware versions.

Unlike iOS, where installing applications is possible only through App Store, Android allows you to download APK files from any sources. This gives freedom, but also opens the door to viruses. Fortunately, modern versions of Android (from Android 10onwards) have built-in security mechanisms, and additional antivirus solutions increase the level of security to 98%. In this article we will look 7 working methodshow to protect your phone from viruses - from basic settings to advanced tools for advanced users.

1. Enabling built-in protection Google Play Protect

Google Play Protect is a standard security tool that scans installed applications for malicious code. It works automatically, but many users don't even know about its existence. You can activate it in a few steps:

1. Open the application Google Play Market.
2. Click on the profile icon in the upper right corner.
3. Select item Play Protect → Settings.
4. Make sure the switches Scan your device for security threats and Improve malware detection are turned on.

Play Protect scans applications not only during installation, but also periodically in the background. However, it does not protect against phishing or fraudulent sites - this requires additional measures.

⚠️ Note: In some regions (such as China), Google services are not available and Play Protect may not work. In this case, use alternative antiviruses from official stores, for example Huawei AppGallery.

2. Installing an antivirus: top 5 applications for Android

Google's built-in protection is often not enough, especially if you install APK files from third-party sources. Antivirus apps offer advanced features such as real-time scanning, phishing blocking, spyware protection, and even VPN for safe surfing. Here 5 proven antiviruses with high ratings in 2026:

• 🛡️ Bitdefender Mobile Security —the best choice in terms of protection and performance. It has a module against data theft and a system vulnerability scanner.
• 🔍 Kaspersky Mobile Antivirus - Russian antivirus with a signature database of more than 300 million threats. The free version scans on demand, the paid version scans in real time.
• 📱 Norton 360 for Mobile - includes protection against fraudulent calls and SMS, as well as a password manager. The subscription covers up to 5 devices.
• 🔒 Avast Mobile Security —the free version offers scanning Wi-Fi networks for vulnerabilities and blocking unwanted calls.
• 🚀 Malwarebytes Security —specializes in removing adware (advertising viruses) and Trojans. Lightweight, does not slow down the system.

When choosing an antivirus, pay attention to:

• 📊 Results of independent tests (for example, from AV-Test or AV-Comparatives).
• 🔄 Database update frequency - outdated signatures will not be able to detect new ones viruses.
• 📱 Impact on performance —some antiviruses drain the battery a lot.

3. Setting up security in Android settings

Even without an antivirus, you can significantly reduce the risk of infection by correctly configuring the system settings. Here are key settingswhich are worth checking:

• 🔐 Block installation from unknown sources:

  Go to Settings → Applications → Special access → Installation of unknown applications and disable permission for all browsers and file managers except trusted ones (for example, Google Chrome or Files by Google).

• 🔄 Automatic system updates:

  Enable automatic download and installation of updates. Many viruses exploit vulnerabilities in older versions of Android. Settings → System → Update systems enable automatic download and installation of updates. Many viruses exploit vulnerabilities in older versions of Android.

• 📱 Data protection when locked:

  In Settings → Security → Locking. screen set a PIN code or pattern of at least 6 characters in length. Fingerprint or facial recognition will add an additional layer of protection.

Important: On devices with root access, the risk of virus infection increases 3 times, since malware can gain superuser rights. If you are not an experienced user, avoid rooting.

4. How to remove a virus if the phone is already infected

If you notice suspicious activity - sudden advertising, rapid battery drain, overheating or unknown applications - your phone is most likely infected. Follow the algorithm:

1. Switch the phone to safe mode:

   Hold the power button, then hold your finger on the option Turn off - a prompt will appear to switch to Safe Mode. Only system applications work in this mode, which will help remove the virus.

2. Check the list of installed applications:

   Go to Settings → Applications sort the list by installation date. Remove all suspicious apps (for example, with names like System Update, Flash Player or Cleaner Pro).

3. Use an antivirus for deep scanning:

   Install one of the antiviruses from the previous section and run a full scan. Some viruses disguise themselves as system files - in this case, only resetting to factory settings will help.

adb shell pm uninstall --user 0 com.example.virus

⚠️ Attention: Some viruses (for example, Xhelper or Shamoon) are restored after removal, as they are registered in the system partitions. In this case, only a complete reset with formatting of the internal memory will help.

5. sites

Viruses are not the only threat. Phishing sites and SMS fraud can steal data from bank cards or social network accounts. Here's how to protect yourself:

• 🌐 Use a browser with phishing protection:

  Google Chrome, Mozilla Firefox or Brave automatically block dangerous sites. In your browser settings, enable the option Safe browsing (Safe Browsing).

• 📧 Check links in SMS and messengers:

  Fraudsters often send messages allegedly from banks or support services (for example, “Your account is blocked, follow the link”). Never enter logins/passwords on sites received via SMS.

• 🔑 Use two-factor authentication (2FA):

  Enable 2FA for all important accounts (Google, VKontakte, Telegram, banks). It is better to use authenticator applications (Google Authenticator, Authy) instead of SMS codes.

Example of a phishing message:

"Dear client! Your *1234 card is blocked. To unblock, follow the link: hxxps://sberbank-security.ru/verify"

Please note:

• 🔗 Unofficial domain (the real Sberbank website is sberbank.ru).
• ⚠️ Urgency ("unblock it urgently!").
• 📛 Lack of personalization (your name or card number is missing).

6. Additional measures: VPN, firewall and permission control

For advanced users who want maximum protection, these tools are suitable:

• 🌍 VPN for encrypting traffic:

  When connecting to public Wi-Fi networks (in cafes, airports) your data can be intercepted. VPN services like ProtonVPN or NordVPN encrypt all traffic. Free versions usually limit the speed or volume of data.

• 🔥 Firewall to block suspicious connections.:

  Applications like NetGuard or AFWall+ (requires root) allow you to control which apps have access to the Internet. For example, you can block access to contacts or geolocation for games.

• 📋 Controlling application permissions:

  Check which apps have access to the camera, microphone or SMS. Revoke unnecessary permissions (for example, why does the messenger need access to your contacts?). Settings → Applications → Permissions Check which apps have access to the camera, microphone or SMS. Revoke unnecessary permissions (for example, why does Messenger need access to your contacts?).

Setting example firewall in NetGuard:

1. Install the application from Google Play.
2. Enable the option Filter traffic.
3. Select applications that you want to block access to the network (for example, games or unknown services).
4. Activate the mode Always onso that the rules work in the background.

⚠️ Attention: Some antiviruses (for example Avast) have a built-in firewall, but it may conflict with other network applications. If you lose internet after installation, check your VPN or firewall settings.

7. Regular maintenance: how to maintain security

Virus protection is not a one-time action, but an ongoing process. monthly checklist to maintain security:

• 🔄 Update applications and system:

  Check for updates. Outdated versions of apps often contain vulnerabilities. Google Play → My applications check for updates. Outdated versions of apps often contain vulnerabilities.

• 🗑️ Delete unnecessary applications and files:

  The more apps are installed, the higher the risk of infection. Use the built-in Optimizer (on Samsung, Xiaomi etc.) to clear the cache.

• 📊 Check your Google account activity:

  On the page myaccount.google.com/security you can see all devices connected to your account and the latest actions (logins, password changes).

• 🔍 Scan your device with an antivirus:

  Run a full check at least once a month, especially if you notice suspicious activity.

Example: If you notice that the battery has begun to discharge faster, and Settings → Battery you can see an unknown application consuming 30% of the charge - this is a reason to check for viruses.

To automate the process, you can use applications like SD Maid (garbage cleaning) or GlassWire (monitoring network activity). They will help you notice suspicious processes in time.
