This is where it's an advantage to setting up an old PC as a firewall 
for your network.  Stick Linux on it, set up your filtering rules, and 
let it sit between your home network and the outside world.  You can 
then have it block that PC's access to the Internet via cron scripts, 
possibly even selectively, between certain times, and there's nothing 
that anything done on that PC (short of a modem with dialup access) can 
do to override that.
