Do not search for "free PDF download" on Google. Those sites often require you to "install" a download manager or a "special e-reader." This is almost always ransomware or adware.
If you want to view content on a mobile device, never install an APK file or a direct download from a website. Only use official app marketplaces: (for iOS devices) Google Play Store (for Android devices)
