It is best to create a line in the hosts file (this is a text file without an extension).

It's here:

C: \ Windows \ System32 \ drivers \ etc \

To block, specify IP: 127.0.0.1 and write the address of the page that will be blocked after a space.

Details on the Internet.

It should be noted that antivirus programs swear at changing the hosts file.

Therefore, you should create a copy of it and store it somewhere separately, and place it in exceptions.
