So my brother is a drug addict. I would like to go onto his computer and set it up so every time he goes to he gets redirected to a drug addiction help website.

I tried changing the "hosts" file but Google Chrome detected the change and wouldn't allow a webpage visit.

Any ideas on how I can do this? Are there any kind of parental controls or Chrome Extensions that would work with this?

He uses Google Chrome.

Also, he uses his Andriod phone to connect to our Verizon Router. Is there any way I can set up the router so he gets redirected to a drug help website? Parental controls on the router only block. Perhaps port forwarding could do the trick?
