CM Cleanmaster is a powerful suite of tools that protects your Android devices from viruses, theft and other threats.

CM Cleanmaster is one of the best antivirus solutions available for Android devices. This threat engine is highly respected in the industry and has been in use and refined from more than 15 years. In addition to identifying malicious apps, it can scan memory as well as SD cards. When it finds a threat, it can root it out, sandbox it and eliminate it.

You can set the app to run on a schedule, so it protects your device without thinking about. Scans are available on demand as well, and the program will automatically update threat definitions. In addition to protecting you from viruses and other malware, it protects you while web browsing, hides chats and other private correspondence and has a find-my-phone feature.

In fact, Cleanmaster is loaded with clever features. For instance, if someone tries to access your device and enters the wrong password or gesture, it will take a selfie of them. You can even set it to notify you immediately via email or another device when such an intrusion happens or when your device moves during a period when it shouldn’t.

There’s not much negative to say about Cleanmaster. It does require Android 5.0 or greater, and it’s a shame there’s not an app this good that can work on devices that only support older versions. It’s also a shame that there are certain features limited to certain devices. Fingerprint lock, for instance, will only work the Samsung Galaxy series of devices.
