So far so good. Running through avast to connect to the internet is seamless. No lag time. I feel 99.9% safe with all the info on my phone. I dont believe anybody can feel 100% safe. Do the housekeeping on your phone and your Avast account, and all should be well. It's up to you to keep up with certain housekeeping like clearing your history. I do get a lot of text messages with links since joining Avast. If there a way to block them before even getting to me? I get 3 or 4 per day.

Hey Jeffrey, where do you get this links to? Messages or mail-box? I believe this has nothing to do with our app, but please be more specific so that we can help. David

Well, apparently this app (or their analog Avast cleanup) deleted almost all of my photos after a cleanup. I choose to delet thumbnails, but because it was "safe" and all that. After that photos in my gallery were not loading, so I cleared cache and boom – they are gone. And it's clearly not something that was suppose to happen. How to restore my photos? No idea) I can't even contact their tech support because yeah why would they make it easy?

Hi Broken, our app should not be able to do this, as it only deletes cache, but we can check it. Please contact us directly from the app's Menu and write us, which app created or acquired the files (e.g. an instant messenger, photo editor, etc.) and if that app was installed at the time that your files were deleted. Thanks, David*Avast

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
