Just curious.
On the Avast Free Antivirus - main panel - lower left hand corner - there is a button “Settings”.
As far as I can tell the “Settings” button doesn’t do anything?
Would be interested to know if it has a purpose.
What Avast version are you using ?
The latest being 18.8.2356 and I don’t see the Settings button on either of my systems. To access the settings on the AvastUI, click the Menu option, top right of the main UI. Or you can right click on the Avast tray icon and select About Avast, that opens the Settings, but at the About Avast section of the settings.
