How to delete empty files with Hexadecimal names on Windows

Question

I have a very vital folder that is being "infested" with unknown files. The 500,000+ files have HEXadecimal Names and most of them are 0 bytes each. This is how the files names look like.

I did a virus scan but found nothing. Incidentally, my original files are still in the folder.

I have tried deleting the strange files via git-bash:

find . -type f -name "[0-9]*" -delete

and also

find . -type f ! -name "*.*" -delete

but it takes so long.

I'm not sure of the regex to use and I don't want to delete my real files and folders. Is there a faster way of removing only those files with the hexadecimal names?
