Please try to put the path C:\ProgramData\Microsoft\Network\Downloader\qmgr.db to scan exceptions; that seems to be the file that (according to the dump) can't be opened and is blocking the scan.
We have a hypothesis what might be the (general) cause and we'll try to modify the scanner to avoid this - but it will take some time.

Hurray! That did it!!

Thank you very much for this. You saved me some money that the Tech Support
guys said that I had to pay for them to run "Advanced Diagnostics" using "a very
sophisticated tool" to see what was wrong with my system.

However, I would expect any programme that works its way through a filesystem,
trying to open/read files, to just flag a file that it cannot open/read
and move on. Perhaps a future update of Full Virus Scan will be modified to do that.

I did see that several Windows updates failed, while others successfully installed.
There is some stuff on the web about problems associated with qmgr.db. I wonder
if the failed updates and the potentially broken qmgr.db are, in some way, connected.

Anyway, thanks a lot for resolving the issue.

Well if opening the file simply failed, then sure, we'd move on... but in this case the operating system's "open" function doesn't return - that's where it gets stuck.

I manually installed Windows Update 1903. Took for ever, but it ran, and it seems to have wiped out all the failed updates as far as what I see in the Reliability Monitor.

Do not know if the failed updates are the sources of the problem, but it may be something for you to consider.

Will follow up this Sunday, when the next Full Virus Scan is scheduled to run.

Thanks again, for your help.

Scheduled Full Virus Scan successfully ran to completion.

Thanks again.
