I had Defender run a scan and it returned with 423 issues. Each issue is "Unknown file in WordPress core." When I select the RESOLVE wrench, each reads:
"We found this file floating around in your WordPress file list but it's not required by your current WP Version. As far as we can tell it's harmless (probably from an older WP install) so you can either delete it or ignore it, up to you! (please be sure to make a backup before you do start deleting files)."
What do you suggest that I do?
Thanks in advance,
