Windows 10: block websites

hello.

i have an annoying set of websites showing ads popping up each time I visit a specific page.
now i have already got the extensions 'ad block' and 'ad block plus' running in the background but on these websites it does not seem to pick up on anything.
i have added the websites to my hosts file but it seems that every time i visit the page it brings up a new website with a different address.
how can i block these websites?

How to Block Websites


I have googled a bit and found software that can be used to block websites on a computer. I also found another way by using Windows which I would prefer. My problem is I must be doing something wrong. Here is the site that has the steps.

Here is what happens when I perform step 6. I am the administrator by the way.





Any ideas on how to make this work?

I have the document in the etc folder





It is still a text file. And it does not block the website. I cannot do what you suggested by saving to docs and changing name. But at least its in the folder. Now how to make it work.
