CM Security Master app review

The Security Master app ships with an intelligent diagnostic tool that scans your phone to identify threats and issues that are affecting its performance. When I opened the app on my Android device, it ran a quick scan operation. SM took about 8 seconds to scan my phone. The only security issue SM found on my device was that I didn’t enable its real-time protection feature.

SM labels issues it has identified as threats. Once it finishes scanning your mobile device, the security app will display a “Remove All” button. Tap on this button to clear the warning messages and eliminate the viruses SM has found on your phone.
