Running Windows 10 Pro, 64 bit and Avast Browser 81.1.4223.139. Had problems with USB ports. Restored System to 6/14/2020 and now Avast Browser doesn't work. It's set to start when Windows starts but it doesn't. Clicking the Taskbar Icon does nothing. Running the AvastBrowser.exe file does nothing. When Windows first starts, Task Manager shows "Avast Browser" and "Avast Browser (32 bit)" but End Task doesn't remove these entries.
I'd like to save my settings, including passwords and bookmarks, and do an uninstall/reinstall. But I don't know how to save these settings.
