Hello, @KimB58.
I appreciate you removing your antivirus application to resolve this error. Did you also attempt to uninstall/install QuickBooks in Selective startup? If not, you can switch to this mode before doing the clean install.
However, it'd be best to consult a Windows expert before you do this task. Also, you'll need to create a backup of your company file and keep a copy of your product and license info before you start.
You can check this article for the detailed steps: Install or uninstall QuickBooks in Selective startup.
Keep me posted on how it goes. I want to ensure you'll be able to fix this in no time. I'll be around if you have follow-up questions or concerns.
