The only fly in the ointment would be the fact that it isn’t recording the scan (Quick Scan), in either the Scan History or the log (even though the generate report option was checked). Sounds like a bug to me.

The Full system was no quicker than the last one I did, in fact is was slower for almost the same number of files, folders and GBs scanned.

EDIT, clarifying that this is only related to the Quick Scan, of the two scans I have tested.
