While instances of Android phones or tablets getting infected by viruses are negligible, it’s better to be safe than sorry, right? If anyone ever told you that Android antivirus apps don’t work, they’re partially right, but most antivirus apps for Android devices also have additional mobile security features which are worth having, even if you aren’t worried about viruses or malware.

Avast is undoubtedly the best Android mobile security app (and not just an antivirus). You get tons of useful features including a virus scanner for apps, a privacy adviser which can intimate you about app permissions which should be reviewed, complete app usage stats so you can analyze patterns to detect suspicious app activity and a web shield which protects your device from malware.
If your device is rooted you can also access the firewall feature which allows you to block certain apps from accessing the internet for added peace of mind. Apart from all this, you also get a comprehensive set of anti-theft tools, using which you can make it impossible for anyone else to uninstall Avast Mobile Security from your device. Moreover, you can set the app to lock your device if it gets lost, display a message on the screen, give you a location via the built-in GPS, start sounding a siren and even wipe all your data remotely. All this is free with reasonable in-app purchases for additional functionality – all in all, we strongly recommend this app for your Android’s security.
