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

You lost a star today. Your app is continually crashing. I see nowhere where I can contact you through the settings. It used to be there but now it's not. People need to be aware that it works intermittently. Not sure I like it YET. And I don't know if I want to pay next year after my paid subscription is over. I see it has a problem updating, it's telling me it's looking for a Wi-Fi connection to update. That's b*******. I went into settings, and it doesn't need a Wi-Fi connection to update.

Satisfied with the actual virus protection. But. Antivirus should do its thing in the background, but this one regularly shoves itself in your face. I have the paid version on both my phone and laptop, but it too often nags me to buy even more. Latest update, you can't close the screen - background operation is expected, but the "Back" button should make the window go away (like a few million other apps do).
