My Windows 10 start menu and task bar are non-functional since Avast updated to 11.1.2245 version on 1/23/2016. Chrome and other non Windows apps are working. Tried several different solutions mentioned in this forum without success and now am trying to uninstall Avast but it won't uninstall. I uninstalled it from the Programs Screen but the uninstaller just froze. Can't get rid of it and it is doing nothing per task manager. I really am not very tech-savvy, so please explain in fairly simple terms.
Thank you very much in advance.
