Like many people, since upgrading to the most recent version, I was receiving the scan cancelled at 99% error. I made the mistake of not checking here first, to find it was just a GUI error, and would be quickly fixed. My bad.
Assuming something else was going on, I chose to uninstall and reinstall the program.
I have 20 TB of storage or so, so, it was not surprising that the initial scan after re-install took about 72 hours. My problem now is, EVERY full system scan, which I have scheduled for 2am every morning, is taking the same amount of time. This was not the case before the re-install. There must be a setting that I chose incorrectly, in the re-install, that advised the program, after initial scan, to only scan altered files, not files that have not changed since last clean scan. Typically, before the re-install, a full scan took a little over an hour.
I thought it might have been the option to store data about scanned files in the persistent cache, so I unchecked that box, but last nights scan was still only 5% or so done, by the time I woke up.
Any other thoughts as to what the issue might be? The product is fairly useless to me if it takes 3 plus days to do a full scan, every single time.
I attempted a ticket with primary support for paid products (ticket 829265), but the response did not address the issue.
Thank you, any and all, for your time and assistance!
