While mobile operating systems are generally secure, phones can still get infected—especially through fake apps, unsafe websites, or malicious links. If your device is slow, shows strange ads, or acts suspiciously, you might be dealing with malware.
Here’s a step-by-step guide to removing a virus from your Android or iPhone, plus how to prevent future infections.
Signs Your Phone Might Be Infected
- Apps you didn’t install suddenly appear
- Battery drains unusually fast
- Your phone is slow or overheating
- You see full-screen ads or pop-ups
- Data usage spikes without explanation
- Browser redirects or strange notifications
Let’s go through what to do if you suspect something is wrong.
For Android Devices
1. Restart Your Phone in Safe Mode
Safe Mode disables third-party apps temporarily.
How to enter Safe Mode (most Androids):
- Hold the power button
- Tap and hold Power Off until the “Safe Mode” prompt appears
- Tap OK
In Safe Mode, check if the suspicious behavior stops. If it does, a third-party app is likely the cause.
2. Identify and Uninstall Suspicious Apps
Go to Settings → Apps → All apps
Look for apps you don’t recognize, especially ones:
- Installed recently
- Without clear icons or names
- Asking for excessive permissions
Uninstall anything suspicious. If you can’t uninstall it, revoke its permissions and try again.
3. Install a Trusted Antivirus App
Install a reputable antivirus like:
- Bitdefender Mobile Security
- ESET Mobile Security
- Norton Mobile
- Malwarebytes
Run a full scan and follow recommendations.
4. Clear Browser Data
If the issue is only in the browser (e.g., pop-ups), clear browsing data.
Chrome:
- Settings → Privacy → Clear browsing data
- Select cache, cookies, and history
5. Factory Reset (if needed)
If nothing works, back up your data and do a factory reset:
- Settings → System → Reset → Erase all data
Be sure to log out of accounts and remove your Google account first, or FRP (Factory Reset Protection) may block access later.
For iPhone Users
iPhones are harder to infect thanks to Apple’s sandboxing, but some malicious profiles or configuration hacks can cause issues.
1. Delete Suspicious Apps
Go to Settings → General → iPhone Storage
Look for apps you didn’t install or don’t use. Tap and delete anything suspicious.
2. Check Safari Settings
- Settings → Safari → Clear History and Website Data
- Disable JavaScript temporarily if pop-ups persist
3. Check for Configuration Profiles
Go to Settings → General → VPN & Device Management
If you see unknown profiles or certificates, delete them. These could be redirecting your traffic or installing adware.
4. Restart or Force Update iOS
Sometimes the issue is temporary. Try:
- Restarting the phone
- Updating to the latest version of iOS (Settings → General → Software Update)
5. Reset All Settings or Erase iPhone
If nothing helps:
- Reset all settings: Doesn’t delete your data
- Full reset: Settings → General → Transfer or Reset iPhone → Erase All Content and Settings
Extra Tip: Don’t Jailbreak or Sideload From Unknown Sources
On both platforms, avoid unofficial app stores or cracked apps. Jailbreaking or sideloading puts your phone at high risk of infection.
How to Avoid Malware in the Future
- Only install apps from the official App Store or Google Play
- Read reviews and check permissions
- Avoid clicking suspicious links in messages or social media
- Keep your OS and apps up to date
- Use antivirus on Android if you sideload apps frequently
Removing a virus from your phone doesn’t have to be stressful. By identifying suspicious apps, cleaning browser data, and knowing when to reset your device, you can restore security and performance without needing expert help.
