What's smbd? It asked the full disc access

Hi, i would ask what is "smbd" (unix executable, Where: Macintosh HD - usr - bin). It's asking me to have the full disc access but i don't know exactly if it's safe or not.

I read somewhere that it should be something linked to windows clients, but i don't know how since i have never connected my pc with my macbook and i don't have parallels. The only thing came to my mind is a common samsung printer which i use with both devices.

I have a 2015 macbook pro.

What do you suggest?

Thanks in advance
