Welcome to the Forum Needs even.
Any time two computers are connected in any fashion; wired or wifi they can infect each other.

Computer worms are one type of malware that specifically tries to spread to other computers. The Wikipedia page has more info.

I can't really answer what you should do because I've taken another approach so I don't have to worry about it - disabled these functions related to LAN traffic:
- File and printer sharing
- Client for Microsoft Networks
- NetBIOS over TCP/IP
- Homegroup and sharing
- Network discovery
- Public folder sharing
and firewall rules related to the above

Network security can be very high tech for experts which I'm not one of them.
I will leave that indebted answer to the experts on such matters.

Tookeri, I like your approach. I am trying to do the same.

My computer keeps get infected on my wifi network. There are some other computers have to regularly connect to that wifi network where I use. If choose not join to any home group of that wifi network, let the computer to be set up as a public one with Network discovery off, will it be safe? thank you all.

I think so. You could also uncheck these 2 in the properties for the Wi-Fi connection

And to be really sure: disable the related rules in the firewall.
