Media Library potential malware | WordPress.org

I have three images in my media library that when deleted immediately recreate themselves. Worse yet when I installed a folder plug-in to manage my media files these image files started replicating and filling up my media library.

I assume this could be malware but I cannot find any information related to the files created. I scanned with Wordfence and it found nothing to report. I do see quite a few WordPress websites with these files via a google search of the file name. The image file names are tdn_pic_1, tdn_pic_2, tdn_pic_3. Does anyone have knowledge or a recommend potential fix to permanently remove them.

I attached a screenshot that shows the three images in question.
