It appears that bitdefender is at least flagging the domain *.w10.site as dangerous.
It came to my attentiin when i shared the link to my website in a telegram group and a other user took a screenshot of him being warned that *.w10.site is dangerous.

Is this already known. And what can i do about this?

My website in question is http://loebas.w10.site.
