The frequency of adds is getting ludicrous. It's an otherwise easy to use app and great for basic virus protection of your phone, but there's nothing phenomenal enough to warrant this. Expect an add; -Before you can launch a scan - After the scan is done -Before it will take you back to the home page. On that topic, some of these adds are malicious. I don't know if they review it or just take money for add space, but I have a different antivirus program just because of that.

Hi Chris, developing apps costs money, so in order to support our operation, we display ads within our FREE version and promote our Premium version, which doesn’t include ads or promotional campaigns. However, we are always collecting feedback and might change the way the ads and notifications are set at the moment. David*Avast

Good security a n VPN service. Hasn't tried to change any settings not authorized. If I give a service any access to all my device settings for security , I will always monitor their activity . I have found in the past that their was unauthorized changes to my device settings as well as changes to my personal account. For example, hanged passwords and deletion of stored fingerprints. I have since deleted the app that I believe to be responsible. Been better though stillspam.

This is for the people who are on a budget like me. Unlike most anti-virus apps in the market, with Avast, upgrading to the paid version is just the beginning of a very long list of upgrades. Each single feature has to be paid separately. For big bucks. Avg anti-virus has the same rating on play store and it's as good, and the whole premium package is for less than a hundred bucks a year. Money doesn't grow on trees!
