Ratings and reviews

I've been using the free version of this app for about 13 years on a wide variety of phones & platforms. I've really had no issues in all that time! Right after an update, the app may be a little glitchy for a day or so, but nothing major. (Just a little slower operating for the first couple hours after updates.) No other issues than that; easy to use, format & setup makes it very easy & straightforward operating. The paid version has a few additional perks, but all in all-great product & app!

I've been using Avast Premium (10 Devices) for almost a week now and so far it's great. I get all the basic security features plus several advanced security features as well. It protects my browsing, wifi, files, emails, phones, computers, apps, and it gives me other cool features like VPN, App Lock, Device Cleanup, Photo Vault, and so much more. As of right now I'm 100% happy with Avast Premium Security. If anything changes then I will be sure to update this review. I recommend it!!!

I've used Avast for probably 25 years, since way back in the late '90s or early 2000s. I've always been pleased with its performance and have rarely encountered a problem while it protected my PCs. It was natural to install it on my Android devices, and even though Android seems to be trouble-free, it does warn of bad websites. One of its best features was the App Killer, but for some reason, they've left it off this version. Avast: Bring back the App Killer!
