Blocking websites

Is there a possible way for me to block a word then have it block every website containing the word. also the word with a sentence?

I.E

Foot

it would also block
Foot Locker

do you mean black list a site which contains the word or the sentence of your choice ?
on the free version ?
adding a patch ?
completing, creating a black list of word/sentence like a censured research for a parental control ?
yes it must be possible but how to ; i will learn it reading the next answers.

Yes, you can do this using the website filter in CIS, however blocking HTTPS is inconsistent so while http://something.com/foot will always be blocked, another website using https://something.com/foot may or may not be. You can find a video of how to configure website filtering for “foot” in CIS here: How to block websites in CIS 7 - YouTube
