This is not an Avast issue but I need some help on this.1809 will update but then it freezes after a few minutes even in Safe Mode.My system runs fine on 1803.Since its not possible to troubleshoot 1809 because it just will not run is there a procedure for getting some answers.Acts like a driver issue but running driver verifier on 1803 finds nothing.MS Communities is no help at all.Clean install and clean boot still makes 1809 freeze.
