madaming way sir para mablock mo yung mga porsites.
first on the list eh using firewall.
you can either choose Internet Properties Restricted sites or using router.
Just in case na wala po kayong Router at "Internet Properties Restricted sites" ang gagamitin nyo, just add those porn sites into it and that's it.
another way to block websites is using HOSTS File:
go to
C:\WINDOWS\system32\drivers\etc
and look for "hosts"
open it with notepad, and follow the examples "all website you want to block should be place after these lines:"
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
example:
127.0.0.1
