Is your Android phone suddenly running slow, showing too many pop-up ads, or installing unknown apps on its own? These are common signs that your device may be infected with malware or a virus.
While Android phones are generally secure, downloading apps from untrusted sources, clicking suspicious links, or installing modified APK files can expose your device to security threats.
In this guide, you’ll learn how to remove a virus from your Android phone safely and prevent future infections.
Signs Your Android Phone Has a Virus
Before removing malware, check if your phone is showing any of these symptoms:
- Frequent pop-up advertisements
- Battery draining unusually fast
- Phone overheating without heavy use
- Unknown apps installed automatically
- Slow performance or frequent freezing
- Excessive mobile data usage
- Browser redirects to suspicious websites
- Apps crashing unexpectedly
- Unwanted notifications from unknown websites
If you notice several of these issues, your device may be infected with malware.
Step 1: Restart Your Phone in Safe Mode
Safe Mode temporarily disables third-party apps, making it easier to identify malicious software.
How to Enter Safe Mode
- Press and hold the Power button.
- Touch and hold Power Off.
- Tap OK when prompted to reboot into Safe Mode.
On some Android devices, the process may vary depending on the manufacturer.
If the problems disappear in Safe Mode, a third-party app is likely causing the issue.
Step 2: Remove Suspicious Apps
Go to:
Settings → Apps → See All Apps
Look for:
- Apps you don’t remember installing
- Fake cleaning apps
- Unknown antivirus apps
- Flashlight or utility apps with excessive permissions
Tap the suspicious app and select Uninstall.
If the uninstall button is disabled, continue to the next step.
Step 3: Remove Device Administrator Access
Some malware gives itself administrator privileges to prevent removal.
Go to:
Settings → Security → Device Admin Apps
or
Settings → Passwords & Security → Device Admin Apps
Disable administrator access for suspicious apps, then uninstall them.
Step 4: Clear Browser Data
Malicious websites can store harmful scripts and notifications.
For Google Chrome:
- Open Chrome.
- Tap the three-dot menu.
- Select History.
- Tap Clear Browsing Data.
- Choose:
- Cookies
- Cached Images
- Site Data
Then clear the data.
Step 5: Remove Harmful Website Notifications
Many users mistake browser notification spam for a virus.
In Chrome:
- Open Chrome.
- Go to Settings → Site Settings → Notifications.
- Remove permissions for unknown websites.
This stops fake virus alerts and unwanted advertisements.
Step 6: Run Google Play Protect
Google Play Protect scans your phone for malicious applications.
To use it:
- Open the Google Play Store.
- Tap your profile picture.
- Select Play Protect.
- Tap Scan.
If harmful apps are detected, follow Google’s recommendations.
Step 7: Update Android
Security updates patch vulnerabilities that malware often exploits.
Go to:
Settings → System → Software Update
Install the latest available update.
Step 8: Install a Trusted Antivirus App (Optional)
If you suspect malware remains, scan your device using a reputable mobile security app.
Popular options include:
- Malwarebytes
- Bitdefender Mobile Security
- Norton Mobile Security
- Avast Mobile Security
- ESET Mobile Security
Avoid downloading antivirus apps from unofficial websites.
Step 9: Reset App Permissions
Malicious apps often request unnecessary permissions.
Go to:
Settings → Privacy → Permission Manager
Review permissions for:
- Camera
- Microphone
- Location
- SMS
- Contacts
- Accessibility Services
Revoke permissions that seem unnecessary.
Step 10: Factory Reset (Last Resort)
If malware persists after trying all other methods, perform a factory reset.
Important: Back up your photos, contacts, and documents first.
To reset:
- Open Settings.
- Go to System → Reset Options.
- Select Erase All Data (Factory Reset).
- Confirm the reset.
After resetting:
- Install apps only from the Google Play Store.
- Restore only trusted backups.
- Avoid reinstalling suspicious apps.
