If you have young persons using your laptop, it might be worth setting some parental controls on your device. These work in a similar way to a firewall. Parental controls can allow or restrict access to parts of your device and the web that may be deemed NOT suitable for young persons. You can even set screen time limits or device curfews which will restrict the young person from using the device for a specific time or maximum usage duration. These are all good things to do to protect young people online.
