Can Malware Transfer Through Wifi?
Yo so I've been wondering since my brother tends to have not so safe internet habits, if potential malware from his laptop can potentially transfer to other devices that also share the same WiFi/network. Also does proximity matter (like side by side Vs in another room). And also if malware could transfer, how to prevent it since I can't control what my brother does. Also I can't do anything router related since it's up to my dad and he doesn't care as much about malware.
Essentially, is it possible? How to prevent it? Is it likely?
