So far, I have used it four times and it has worked well. The interesting thing about this app is that when it does scan it shows little icons moving up and down. It's entertaining.
In so far as I have used it, I haven't had any security breaches but I am pretty sure it's working since it goes as far as to check the internet security.
Get the app: Avast Mobile Security & Antivirus (Android)
As of this writing this antivirus protection and security is free on the Amazon Appstore. Get it while you can!
