I have 2 laptops in my home, and my mother has a desktop, and sometimes a visitor will bring their own laptop. We all connect to the same modem, and sometimes the same printer.
We have no need for file sharing.
Sometimes one computer will be infected, and I worry that this infection might spread to other PC's that happen to be using the modem.
In one laptop, which I bought recently, I asked the person who set up windows to set it up for "public" on the theory that public networks do not trust files from other PCs, and so would not trust viruses from other PCs.
But he strongly objected, saying that "public" is less secure.
Other people have said its MORE secure.
I just installed windows 10, and that added a complication, because the default behavior is to attach to any network in the neighborhood.
So my questions:
1) what are the choices: are they: public/private/home?
2) which should I use (public/private/home), given that malware infections happen often in this house, and I don't want them to spread because one PC "trusts" another PC.
