Introduction
With the increasing reliance on smartphones for daily tasks, Android devices have become prime targets for cyber threats. Malware and viruses can compromise personal data, slow down device performance, and even lead to financial loss. To safeguard your Android phone, it’s crucial to implement security measures that prevent malicious attacks. In this article, we will explore effective strategies to protect your Android phone from malware and viruses.
1. Keep Your Android System Updated
Android regularly releases security patches and system updates to fix vulnerabilities that cybercriminals may exploit. Always update your device to the latest version to stay protected.
How to Update:
