Question about Norton DNS & Webshield?

Hello I live in The Netherlands. I wanted to use the DNS of Norton by installing the software , but then i got a message that it only can be used on English OS's

 

But if i do it manually , will it work then ? Does Norton DNS support The Netherlands ? 

 

 

And my next question,

 

I have at the moment no DNS from Norton , i use my own DNS from my ISP.

 

But how does Norton block malicious websites and other dangers on the web if i have no Norton DNS ?

 

Does it have a webshield ?
