How to Check for Malware on Android
Checking for malware on Android is the process of scanning your device for harmful apps, spyware, and security threats using built-in tools or antivirus software.
Users need this when experiencing battery drain, pop-up ads, or suspicious activity on their Android device.
This guide covers 7 steps requiring 5-10 minutes and Android 8.0 or later.
Prerequisites
Required tool: Android device (version 8.0 or later recommended)
Necessary resources: Active internet connection, Google account linked to device
Time estimate: 5-10 minutes
Skill level: Basic familiarity with Android Settings menu
Step 1: How Do You Access Google Play Protect Scanner?
Open Google Play Store, tap your profile icon (top-right corner), select Play Protect from menu, tap Scan button. Google Play Protect scans all installed apps for malicious software, displaying results within 30-60 seconds with threat notifications if malware detection occurs.
Action:
1. Exact location: Google Play Store app > Profile icon (circular, top-right) > Play Protect
2. Exact button: Blue “Scan” button below “App status”
3. Expected result: Scanning animation appears, followed by “No harmful apps found” or threat alert with app names
Purpose:
Google Play Protect is Android’s built-in virus scan that runs automatically but manual scans detect recent mobile app security threats immediately.
Step 2: How Do You Review Play Protect Scan Results?
After scan completes, review results screen showing scanned apps count, last scan time, and detected threats. Tap any flagged harmful apps to view threat details, then select Remove or Uninstall to eliminate malicious software from your device immediately.
Action:
1. Results location: Play Protect screen displays “X apps scanned” with timestamp
2. Threat details: Red warning banner shows “Harmful app detected” with app name and threat type (spyware, adware, trojan)
3. Removal options: “Remove” button (orange) or “Uninstall” button for each flagged app
Purpose:
Understanding scan results helps identify which apps contain malware and what type of security threat they pose to your device security.
Step 3: How Do You Check for Suspicious Apps Manually?
Navigate to Settings > Apps, scroll through complete app list, identify unfamiliar apps you never downloaded or apps with generic names like “System Update” or “Security.” Check installation dates, data usage, and permissions to spot malicious apps hiding as legitimate software.
Action:
1. Navigation path: Settings app > Apps or Application Manager > See all apps (shows complete list)
2. Suspicious indicators: Apps with no icon, misspelled names (“Gooogle”), excessive permissions, high battery or data usage despite minimal use
3. Verification steps: Tap suspicious app > check Install date, Permissions, Storage usage, Battery consumption
Purpose:
Manual inspection catches malware that automated scans miss, especially spyware and adware disguised as system apps.
Play Protect detection rate sits around 55-70% according to independent testing, making manual checks necessary for comprehensive device protection.
Step 4: How Do You Monitor Unusual Battery and Data Usage?
Access Settings > Battery to view apps consuming excessive power, then check Settings > Network & internet > Data usage for apps transmitting abnormal data amounts. Malware often runs background processes that drain battery faster than normal and sends data to remote servers without user knowledge.
Action:
1. Battery check path: Settings > Battery > Battery usage (shows percentage per app for last 24 hours)
2. Data usage path: Settings > Network & internet > Data usage > Mobile data usage or Wi-Fi data usage
3. Warning signs: Unknown apps using 10%+ battery, apps consuming 100MB+ data with no legitimate reason, background activity when app should be idle
Purpose:
Monitoring resource consumption reveals hidden malware performing unauthorized activities like cryptocurrency mining, data theft, or ad fraud.
Step 5: How Do You Check Device Administrator Apps?
Navigate to Settings > Security > Device admin apps to view which apps have administrator privileges on your Android device. Malware frequently grants itself admin access to prevent uninstallation, making this check crucial for removing stubborn infections.
Action:
1. Exact navigation: Settings > Security (or Security & location) > Other security settings > Device admin apps
2. Admin list review: Check for unfamiliar apps with admin privileges (legitimate ones: Find My Device, work profiles, security apps you installed)
3. Deactivation process: Toggle off suspicious app > tap Deactivate > uninstall the app through normal methods
Purpose:
Ransomware and trojans use device administrator privileges to resist removal attempts and maintain persistent control over your device.
Step 6: How Do You Install and Run Third-Party Antivirus Scanner?
Open Google Play Store, search for Malwarebytes, Avast Mobile Security, or Norton Mobile Security, install your chosen antivirus app, open it, tap Scan Now. Third-party scanners detect threats Play Protect misses using different detection algorithms and updated malware databases.
Action:
1. Installation: Google Play Store > search “Malwarebytes” or “Avast Mobile Security” > Install (verify publisher name matches official developer)
2. Scan execution: Open antivirus app > accept permissions (storage, accessibility if needed) > tap “Scan” or “Scan Now”
3. Results handling: Review detected threats list, tap “Remove” or “Quarantine” for each item, follow prompts to delete infected files or close malicious apps
Purpose:
Third-party antivirus tools achieve 95-100% detection rates for known malware versus Play Protect’s 55% rate, providing stronger protection.
Kaspersky, AVG, and ESET also offer reliable mobile app security scanning capabilities.
Step 7: How Do You Boot into Safe Mode for Verification?
Press and hold Power button until power menu appears, long-press “Power off” option until “Reboot to safe mode” prompt displays, tap OK. Safe Mode disables all third-party apps while keeping system apps active, helping isolate whether downloaded apps cause malware symptoms.
Action:
1. Safe Mode entry: Power button (hold) > long-press “Power off” text (not icon) > tap “OK” on safe mode prompt (Samsung: Power + Volume Down simultaneously during boot)
2. Visual confirmation: “Safe mode” watermark appears in bottom-left corner of screen, only pre-installed apps load
3. Testing process: Use device normally for 5-10 minutes, check if pop-up ads, battery drain, or suspicious activity stops
Purpose:
If symptoms disappear in Safe Mode, recently installed apps contain malware; if problems persist, system-level infection or hardware issues exist.
Verification
Run Google Play Protect scan again after completing all removal steps. Device should show “No harmful apps found” message.
Check battery usage returns to normal levels (screen should be top consumer, not unknown apps).
Monitor data usage for 24 hours to confirm no suspicious background transmissions occur.
Verify device administrator list contains only legitimate apps you recognize and trust.
Test device performance improves with faster app loading, no random crashes, eliminated pop-ups.
Troubleshooting
Issue: Play Protect scan finds no threats but phone still shows malware symptoms
Solution: Install Malwarebytes from Google Play Store > run full system scan > manually review Settings > Apps for unfamiliar entries > clear cache for suspicious apps before uninstalling.
Issue: Cannot uninstall suspicious app
Solution: Settings > Security > Device admin apps > deactivate app’s administrator privileges > return to Settings > Apps > select app > Force Stop > Uninstall (if still fails, boot to Safe Mode first).
Issue: Malware persists after removal attempts
Solution: Back up photos, contacts, important files to Google Drive or external storage > Settings > System > Reset options > Factory reset > Erase all data (this removes all content including malware but cannot be undone).
Reinstall apps only from Google Play Store after factory reset completes.
Avoid restoring from backup if backup contains infected apps.
Next Steps
Enable automatic security updates: Settings > System > System update > turn on automatic downloads.
Review and limit app permissions regularly to prevent unauthorized access to sensitive data.

1. Battery check path: Settings > Battery > Battery usage (shows percentage per app for last 24 hours)
2. Data usage path: Settings > Network & internet > Data usage > Mobile data usage or Wi-Fi data usage
3. Warning signs: Unknown apps using 10%+ battery, apps consuming 100MB+ data with no legitimate reason, background activity when app should be idle
Purpose:
Monitoring resource consumption reveals hidden malware performing unauthorized activities like cryptocurrency mining, data theft, or ad fraud.
Step 5: How Do You Check Device Administrator Apps?
Navigate to Settings > Security > Device admin apps to view which apps have administrator privileges on your Android device. Malware frequently grants itself admin access to prevent uninstallation, making this check crucial for removing stubborn infections.
Action:
1. Exact navigation: Settings > Security (or Security & location) > Other security settings > Device admin apps
2. Admin list review: Check for unfamiliar apps with admin privileges (legitimate ones: Find My Device, work profiles, security apps you installed)
3. Deactivation process: Toggle off suspicious app > tap Deactivate > uninstall the app through normal methods
Purpose:
Ransomware and trojans use device administrator privileges to resist removal attempts and maintain persistent control over your device.
Step 6: How Do You Install and Run Third-Party Antivirus Scanner?
Open Google Play Store, search for Malwarebytes, Avast Mobile Security, or Norton Mobile Security, install your chosen antivirus app, open it, tap Scan Now. Third-party scanners detect threats Play Protect misses using different detection algorithms and updated malware databases.
Action:
1. Installation: Google Play Store > search “Malwarebytes” or “Avast Mobile Security” > Install (verify publisher name matches official developer)
2. Scan execution: Open antivirus app > accept permissions (storage, accessibility if needed) > tap “Scan” or “Scan Now”
3. Results handling: Review detected threats list, tap “Remove” or “Quarantine” for each item, follow prompts to delete infected files or close malicious apps
Purpose:
Third-party antivirus tools achieve 95-100% detection rates for known malware versus Play Protect’s 55% rate, providing stronger protection.
Kaspersky, AVG, and ESET also offer reliable mobile app security scanning capabilities.
Step 7: How Do You Boot into Safe Mode for Verification?
Press and hold Power button until power menu appears, long-press “Power off” option until “Reboot to safe mode” prompt displays, tap OK. Safe Mode disables all third-party apps while keeping system apps active, helping isolate whether downloaded apps cause malware symptoms.
Action:
1. Safe Mode entry: Power button (hold) > long-press “Power off” text (not icon) > tap “OK” on safe mode prompt (Samsung: Power + Volume Down simultaneously during boot)
2. Visual confirmation: “Safe mode” watermark appears in bottom-left corner of screen, only pre-installed apps load
3. Testing process: Use device normally for 5-10 minutes, check if pop-up ads, battery drain, or suspicious activity stops
Purpose:
If symptoms disappear in Safe Mode, recently installed apps contain malware; if problems persist, system-level infection or hardware issues exist.
Verification
Run Google Play Protect scan again after completing all removal steps. Device should show “No harmful apps found” message.
Check battery usage returns to normal levels (screen should be top consumer, not unknown apps).
Monitor data usage for 24 hours to confirm no suspicious background transmissions occur.
Verify device administrator list contains only legitimate apps you recognize and trust.
Test device performance improves with faster app loading, no random crashes, eliminated pop-ups.
Troubleshooting
Issue: Play Protect scan finds no threats but phone still shows malware symptoms
Solution: Install Malwarebytes from Google Play Store > run full system scan > manually review Settings > Apps for unfamiliar entries > clear cache for suspicious apps before uninstalling.
Issue: Cannot uninstall suspicious app
Solution: Settings > Security > Device admin apps > deactivate app’s administrator privileges > return to Settings > Apps > select app > Force Stop > Uninstall (if still fails, boot to Safe Mode first).
Issue: Malware persists after removal attempts
Solution: Back up photos, contacts, important files to Google Drive or external storage > Settings > System > Reset options > Factory reset > Erase all data (this removes all content including malware but cannot be undone).
Reinstall apps only from Google Play Store after factory reset completes.
Avoid restoring from backup if backup contains infected apps.
Next Steps
Enable automatic security updates: Settings > System > System update > turn on automatic downloads.
Review and limit app permissions regularly to prevent unauthorized access to sensitive data.
Download apps exclusively from Google Play Store, never from third-party websites or unknown sources.
Consider additional protection measures covered in mobile app security best practices and security checklist guides.
Schedule monthly malware scans to catch infections early before significant damage occurs.
