This is likely due to your virus scanner. If those files contain
non-executable content, it is probably safe to disable virus scans for
those files.

Something that ls does is triggering the scan. That scan causes the
virus scanner to read the entire file. You should see extraordinary
GPU and disk activity for some time after the ls completes. There
might be processes or at least threads for each file being scanned.

Hopefully you will be able to identify a common folder in the path to
those files where it is safe to disable scanning for that folder and
all folders and files within that folder.
