Here's the Windows Defender thread:

Something is blocking MC. A directory that's read only, for example.
This is a new computer with a completely new installation of MC25. I got it from HP 2 days ago. All I did was install MC, copy the files to the drive and restore a backup.
The image files can be displayed with no problem. There is no read problem for those files. The only problem is building the thumbnails. And, one of them from one of the same folders, for a small image file, did build. How did that small file build if there is a read only problem? As far as I know, the only writing having to do with thumbnails is totally under MC control. If there is a read only problem, where would you suggest it is? And the Audio thumbnails build fine and I think the image thumbnails are stored in the same place.
I posted my Defender exclusions, which, according to that tread, should be fine. If there is something wrong with the exclusions that I posted, please let me know. If anyone has a suggestion, based on what I posted, please let me know.
This is a vanilla installation and I have followed what I believe are the correct procedures. Yes, something is blocking the image thumbnails but it is not blocking the audio thumbnails. Any suggestions based on what I have posted to solve this problem are welcome.
Thanks for your help.
