They are not rogue networks when you are presented with a list of Access Points to connect to. It is common to show a list of all of available SSID's that would be able to connect to. It gets really bad in public places, when people use their Smartphones as WiFi Access Points.
You cannot remove any of the SSID's that are listed on the Network connections. You just have to live with it, when you are using your laptop or tablet in public places. Just make sure that you have File Sharing turned off.
Now if you are seeing a list of other users folders, when you open up Explorer and go to Shared folders. Then you have an issue with either you are connecting to a rogue hotspot, or the person that set up the hotspot is just an idiot and does not know how to manage it properly.
Use a strong computer log in password, make sure your Firewall is enabled when on Public networks, do not publicly share any files or folders.
