Hiya and welcome to Tech Support Guy 
Have you seen this:
https://support.google.com/websearch/answer/186669
And this section:
Map google domains to forcesafesearch.google.com
You may want to keep a copy of the hosts file as well, just save it to your documents, just in case you ever need to amend things.
Thanks
