1. Keep Your Device Updated
Ensure your device is running the latest version of Android. Manufacturers regularly release updates that include security patches, closing vulnerabilities exploited by malware.
2. Download from Trusted Sources
Stick to official app stores like Google Play. Enable Google Play Protect, which scans apps for malware and provides warnings about potentially harmful apps.
3. App Permissions
Review app permissions before installation. Avoid apps that request unnecessary access to your data, contacts, or location.
4. Install a Reputable Antivirus App
Choose a well-known antivirus app from a trusted developer. These apps offer real-time scanning and protection against known malware.

6. Regular Backups
Frequently back up your device to the cloud or an external storage device. In case of a malware attack, you can restore your data.
7. Stay Informed

Signs of Android Malware Infection
Despite your best efforts, you may still encounter Android malware. Recognizing the signs of infection early can mitigate damage:
1. Unusual Battery Drain
Excessive battery usage can indicate background malware activity.
2. Data Usage Spikes
Malware may send or receive data without your knowledge, leading to increased data usage.
3. Sluggish Performance
If your device suddenly becomes slow or unresponsive, it could be due to malware consuming system resources.

Frequent pop-up ads, even when you’re not using apps, could be a sign of adware.
5. Unauthorized Access
If you notice unfamiliar apps, settings changes, or new accounts on your device, it may be compromised.
What to Do if Your Android Device is Infected
If you suspect malware infection, take immediate action:
1. Disconnect from the Internet
Disable Wi-Fi and mobile data to prevent the malware from communicating with its servers.
2. Uninstall Suspicious Apps
Remove any recently installed apps that you suspect may be causing the issue.
3. Run a Full Scan
Use your antivirus app to scan your device thoroughly and remove any detected malware.
