status after scan

For the last few months, I’ve been getting the status “Error:The file or directory is corrupted and unreadable(1392)” on 4 filenames starting with
"c:\Windows\assembly\nativeimages_v4.0.30319_32".
I haven’t worried about it as there are no threats found during the scan, but these 4 messages keep appearing after every scan.

Any advice please ?
