After PC, Android devices need extra protection from thieves and hackers attacks, recent reports state that Android attacks anonymously increased in the recent years. Avast launched its latest Mobile Security and Antivirus for Android. The latest version of Avast Mobile Security built with a bunch of very useful utilities.

Avast can replace some apps like Applocker, Bandwidth monitor, Anti-Theft, Backup, Privacy Advisor, Application management and SMS and Call filter. The AV test results are very good and protection score is 6.0/6.0.

The user interface is pretty much easy to understand, it shows the categories list to start, the main categories are

It thoroughly scans my entire phone in 3 min, the time varies when you click on only App scan, it can complete scan in one minute, the remaining time is depending on your SD card size. Avast uses File Shield technique, it scans your every file in your Android device.


When we lost the device, the biggest threat comes in our mind is data loss. Even we claim the mobile by insurance, but the data we can’t. Avast Anti-Theft feature comes in Avast Mobile Security and Antivirus but you need to install it separately.

Anti-Theft feature available in Google Play store, no need to search for the app, you can find directly when you click on the Anti-Theft tab it asks you to download it from play store. The Anti-Theft app will download as an update agent and sizes 6.26MB.
