First Screenshot, delete everything that does not contain:

• adobe
• google
• jamf
• microsoft
• native-instruments
• oracle
• reincubate
• rogueamoeba

Second Screenshot, delete everything that does not contain:

• epicgames
• valvesoftware

Third Screenshot is fine

In the first screen shot, I did include com.optimize.speed.device.plist to be deleted simply because optimizers are not recommended. In the second screenshot I also included com.informer.mac.client.plist to be deleted, but if you do use that app it may be fine to leave and not necessarily causing the problem you are seeing. Instead of deleting all these files immediately, you can move them into a temporary folder on your desktop just to make sure there are no unwanted changes in those apps that you use. Just a FYI, I am sure you are aware that jamf is MDM (Mobile Device Management) software.

After that, restart your computer again normally and that alert will be gone.

If you can identify the file named "BasicIndex.gqa," move it to the Trash. Empty the Trash afterward.
