If you feel a website is inappropriate, a waste of valuable time, or disturbing in some way, you can block websites on Android using one of several apps designed to block unwanted content.

Apps featured in this article work on Android phones and tablets running Android 5.0 Lollipop or higher.

How to Block Websites on Android Using a Security App

There are many apps that give you the flexibility to block websites you feel are inappropriate, but why just protect yourself from the threats you know about? While you’re blocking unwanted websites, add an extra layer of protection and install a security app that provides safeguards against viruses, ransomware, and other malicious content.

  • Helping you find your phone if it gets lost.
  • Helping recover from a ransomware attack.
  • Wiping your device.

Mobile Security is free to download and its anti-virus and anti-malware features are free to use.

Registration with Trend Micro is also required to continue using the app.
