How can I protect my Android device from downloading malicious APK files, including webcomics free APKs?

To protect your Android device, only download apps from the Google Play Store. Enable Google Play Protect, which scans apps for potential threats. Avoid clicking on suspicious links or pop-up ads that offer free downloads. Be cautious about granting excessive permissions to apps. Keep your operating system and apps updated to patch security vulnerabilities. Install a reputable antivirus app and regularly scan your device for malware. Finally, avoid enabling 'Install from unknown sources' unless absolutely necessary and only do so for trusted sources.
