How can I report or remove potentially harmful modded APKs like 'Pathan KPK 42000 Blogger Mod APK' from my device?

To remove a modded APK, go to your device's 'Settings' > 'Apps' (or 'Application Manager'), find the specific app, and select 'Uninstall'. If you downloaded it from a website, also consider clearing your browser cache and history. If you suspect it's deeply integrated or causing persistent issues, a factory reset might be necessary, but ensure you back up important data first.
