I don’t really know what info avast stores where as I’ve only started using it the last couple of weeks. However the notification started appearing after I’d added a dialog to the app I’m working on. I’ve attached the UITracking.log, there’s entries about dialogs in there, I don’t understand them yet. Hopefully that’s helpful. I’ll see what other logs there are.
Not to worry, I had to uninstall avast unfortunately. Started eating 99% cpu. It was disabled at the time and it didn’t appear to be an update as it went on until I rebooted.
