or can/must iIchange the logging settings to get a report by rightclick-scan ? logging is now set to "Alert"

These entries are written to the ‘Warning’ category of the log.
So in order to have them, you need to move the Logging Level slider at least to Warning (or below).

If you have avast Pro, there’s a better option - in Enhanced UI, you can edit the task Explorer Extension, and turn on generation of report file for it.
