I've been using the premium version of this app for approximately a decade. I will not be renewing. The app now requires full-time location access to use the scan wifi feature. Unless you give this permission, you are unable to use the feature. I'll look at alternative at renewal, but I'm cancelling my renewal today. Response: Then why is location services required full-time and not just when the app is being used? The developer did not answer my question.

Hi Donald, these are the regulations - nothing much we can do about it. David

Upon renewal, thee software does not perform the same, and every time I opened the software I have to deal with an obnoxious ad for online casino gaming. I was not only forced to endure watching the ad but had to go thru GooglePlay to stop it. I notified Avast to cancel, which they did - as of 1/25/26 - but said NO REFUND DUE! As I couldn't use the program, & cancelled within 2 days of renewal, a full refund is reasonable. Therefore, given no choice, I have disputed these charges with my bank.

Hi Lynne, we are very sorry to hear about your inconvenience. This will probably require some dialogue with our Support Team though, which may be a difficult task here on Google Play. Can you please contact us on https://support.avast.com and describe your problem in detail? Thanks, David*Avast

Email Guardian fails to load on restart or after shutdown & your VPN interferes with the performance of several of my other apps, so it has to be turned off. In the past several years that I've had a PAID subscription, there's always some kind of problem with your security suite. With the VPN shut-off, I get voice mail again. If I turn on the VPN, i don't get voice mail. BTW, I've attempted several times contacting technical support,but never get a response.
