Quick/EASY PEACE OF MIND If you're looking for something quick and easy to navigate then tap install. It directs you through the entire set-up and explains everything (for us non tech people 😉). Now I can be at peace knowing my info is protected. Granted NOTHING is 100% ,but when you have protection it makes it more difficult for those "bad people and apps". This tends to cause them to move on to an easier target. Good luck and stay safe. Mostly, use your common sense. 😀😉😉

Confidence with a catch. I appreciate the virus scans, but the app is always trying to upsell you. It lets you run all these different scans but then you need to purchase an upgrade to use them. I've been a loyal customer for almost a decade, but I don't like the hassle. EDIT based on reply: I am a paying customer. Not using the free version.

Hey Luke, we find it fair to offer top level protection for free and more advanced features for a little fee. Thanks for understanding. The basic scan and cleaning are offered within the free version. David

The app is working great. It scans and reports/flags any issues. Unfortunately, I dont think it can detect a cloned sim or a remote hack. I am not sure. I was hoping I would be notified by Avast for this issue if it was happening. It does not seem to check for these issues. Avast works great for keeping phone virus free. I will continue to use the premium bundle as I do feel secure when it's running. Def worth the $, but I do wish it could detect or notify of cloning or remote hacking.

Hey Trenton, our app doesn't have any "anti-hacker" solution. It detects malware and boosts security, but a usual hacker attack does not use malware to get into your device. To minimize the chance of a succesful hacker attack, we recommend to use the Avast SecureLine and check your Privacy Advisor. David*Avast
