You see this warning message when Trend Micro scans your home network:
Why did this happen?
If there are more than 30 devices connected to the network, it is considered a public network.
If you are connected to a public network, whatever you do online could also be visible to others. They could see what websites you are visiting, read your emails, or see passwords you enter.
What should I do next?
Connect your computer to a home network or manually add a device to protect.
