If you want the website blocking to occur on your PC only, you may do the "hosts file method".
1. Run Notepad as Admin.
2. Open the hosts file located at C:\Windows\System32\drivers\etc using Notepad
3. Place your cursor at the very last part then press "enter". (Tip: Press Ctrl + End, then Enter)
4. Let's say you want to block a site with a domain "philmusic.ph", do it by typing "127.0.0.1 philmusic.ph" or just to make sure, type the same address on a new line below except that the second one has a "www" prefixed. e.g "127.0.0.1
www.philmusic.ph"
Sample:
127.0.0.1 philmusic.ph
127.0.0.1
www.philmusic.phIf you want to add another site, just type it below the existing addresses using the same format.
5. Save your file as a hosts file, NOT a text file.
127.0.0.1 refers to your localhost, this is used to loop back addresses to the machine (computer). Hope this helps
