Okay, thank you @MrMadness

 

Let's go ahead and run a couple of scans and get some updated logs from your system.

Please make the following changes.

• Temporarily disable Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the scans are completed.
• Disable-Fast-Startup
• Show-Hidden-Folders-Files-Extensions

 

Next, run these steps and post back the logs as an attachment when ready.
