In this article, we explain how to prevent unwanted websites from appearing on Android devices by using free security apps, website blockers, and firewalls.

While you're blocking unwanted websites, you can add an extra layer of protection and install a security app that provides protection against viruses, ransomware, and other malicious content.

For example, Trend Micro's Mobile Security and Antivirus protects against malicious content and blocks unwanted websites with parental controls. Other features include:

Mobile Security is free to download, and its anti-virus and anti-malware features are free to use. The parental controls require a $30 annual subscription after a free trial. Registration with Trend Micro is also required to use the app.
