Paid them for a year and it can't even remove the malware on my phone. What a scam. Response: I already tried that. When your app didn't work I canceled my subscription. Even though I paid for the FULL YEAR it just removed the subscription entirely. Update 2: I can't reach out support is a subscription only feature. Which I no longer have despite paying for a full year. I want a refund. I can't believe canceling a subscription renewal removes what you paid for.

Hi, this issue will probably require some dialogue with our Support Team, which may be a difficult task here on Google Play. Can you please contact us on android@avast.com and describe your problem in detail? Thanks, David*Avast

Update. Still 5 stars but since I have reinstalled Avast again I am having problems saying the app is malfunctioning and is not working. At the end of my last subscription I had this so much it felt the same as not being protected at all. I really like this app. I went to my phone carrier and they could not find anything inferring. Help!!!! Also only one more feature would make this an absolute must have...... Taking a picture when someone tries unlocking/ snooping on devices. Is it possible?

PRO TIP: best overall security app for mobile devices. | Avast has been keeping my devices safe for nearly a decade and it doesn't have a huge performance hit. It's fairly unobtrusive, sits quietly in the background, and ensures the safety of my mobile devices. The developers are responsive to any issues that have come up over the years. The paid version of the app is definitely well worth the price, especially for the peace of mind it brings.

Hi Peter, the app actually does remember the network, but asks you to rescan it every 30 days, just to check for any changes in the network's configuration. Have you tried to disable some of the notifications? (Menu--Settings--Notifications) Tereza*Avast EDIT - Thanks for updating your comment, I have forwarded it to the team.
