Before removing anything, you need to confirm whether your phone really has malware or just too many apps running in the background.
Here are clear signs that your Android phone may be infected:
- Apps keep crashing for no reason.
- You see ads or pop-ups even when no app is open.
- Battery drains faster than usual.
- Your data usage suddenly spikes.
- The phone heats up even while idle.
- Unknown apps appear on your home screen.
If you notice two or more of these, it’s time to take action.
How to Check If You Have Malware Using Settings
- Open Settings → Apps → See all apps.
- Scroll through the list and look for any unknown or suspicious app names especially those installed recently.
- Tap on the app and check Permissions. If it has access to things like messages, location, or storage without reason, that’s a red flag.
- Go back to Settings → Battery → App usage. Apps draining abnormal power could also be malware.
If you’re unsure, Google the app name to see whether it’s legitimate.
How to Remove Malware from Android Phone (Step-by-Step)
Once you’ve confirmed that malware is present, don’t panic. Follow these safe and free steps to remove it permanently.
Step 1: Boot Your Phone into Safe Mode
Safe Mode starts your Android phone without running third-party apps which is perfect for deleting malicious ones.
Here’s how:
- Press and hold your power button.
- On-screen, tap and hold “Power off” until you see “Safe Mode.”
- Tap OK to reboot.
Once in Safe Mode, you’ll see “Safe Mode” in the corner. Now only system apps will run.
Step 2: Delete Suspicious Apps
Now that malware can’t auto-run, it’s safe to uninstall.
- Go to Settings → Apps → See all apps.
- Find the suspicious app.
- Tap Uninstall.
- If “Uninstall” is greyed out, first go to Settings → Security → Device Admin Apps, and disable its admin rights.
Repeat for all unwanted or unfamiliar apps.
Step 3: Clear Cache and App Data
Even after uninstalling, leftover files might stay hidden.
- Go to Settings → Storage → Cached data → Clear cache.
- Then open Files by Google or your phone’s File Manager.
- Delete junk and suspicious folders manually (avoid deleting system folders).
This step helps wipe any hidden malware traces.
Step 4: Use Google Play Protect
Google’s built-in security scanner is actually effective if used properly.
- Open the Play Store.
- Tap your profile icon → Play Protect → Scan.
- Wait for it to scan your phone.
- If it flags any app, tap Uninstall immediately.
Play Protect keeps running in the background, so keep it on.
