What's the best Android app for comprehensive device protection that includes antivirus and performance optimization?

McAfee® Security for T is designed specifically for T-Mobile Android users who need all-around device protection without juggling multiple apps. The app's core strength lies in its real-time antivirus scanning that automatically checks new installations and existing apps for malware threats. For performance optimization, the app includes a junk file cleaner that removes cached data and residual files, potentially freeing up significant storage space on devices with limited capacity. The Wi-Fi security feature automatically scans networks for vulnerabilities when connecting to public hotspots, which is particularly useful for travelers or students using campus Wi-Fi. Users report the app runs lightweight background scans without noticeably slowing down device performance, though some note the interface could benefit from more intuitive navigation between security and optimization sections. The app also provides app permission monitoring and anti-theft features, making it a practical choice for users who want consolidated security management rather than separate specialized tools.
