Thank you for your comments.
I made sure that all the (Report file - Generate Report file ) settings were turned on.
I was also able to locate C:\ProgramData\AVAST Software\Avast\report (my fault , I had to make sure it was showing hidden files)

Now after running a scan:

  1. the logs show up in the C:\ProgramData\AVAST Software\Avast\report

  2. HOWEVER, they still do not display in the AVAST User Interface Scan Log page!

Oh well, at least I can hunt them down outside the UI.

Wonder if anyone else is having this issue? Or is it just me?

Thanks again for your insight. It is greatly appreciated.
