Can you protect your home network from bad guys?

For home users, over the last few years, there’s been different ways to protect your home network from malware. In the past installing a computer based antivirus/malware protection was enough, but what about now where homes routinely have smart devices, multiple phones, tablets, cameras, or home video streamers, where installing antivirus is impractical or not possible at all (anyone know how to install antivirus on a Roku?)? I go thru the 3 primary different types, and give you my recommendations based on your budget or purchase history.

There won’t be any product links this time since I’m not really reviewing a particular product.
