junjun it sound like you are going down a list of question on a homeword assignment.
What courses are you taking?

To put it simple.
Anything that is infected when hooked to a computer, network, domain can infect all if the infection is created/programed correctly.

I am not on any assignment merely wanted to learn more about network security for better protection. I am often helping my relative on computer matters so I thought it better to learn and set up properly for them. Btw I study on making of 3d animation.

As for my previous question which I will write again below for easy reference, it is not about infected computer, this is about a normal not infected computer.

All network requires a security key before you can enter right?

Because whenever the wifi is turn on you will be able to choose which network to connect to, if you accidentally press a wrong network will you be able to connect to it? is it possible for someone to disable the security key hence allowing everyone to connect to it. This is a big worry because some people especially old people with bad eye sight might accidentally press and connect to a wrong network without realising it.

In my opinion all the security key in the world might not help once a system is infected. Once a infection has entered a system it could steal the security keys and continue on it nasty job.
You will never get all the possibilities of what might happen, could happen, won't happen on a forum. Their are volumes of books wrote on the subject.

No... because not all networks are wireless. An infected computer can join a wired network (think about a school network) and start the process of breaking into (and infecting) other computers.

If you want to talk about wireless networks (as found in most homes), the key can be determined (without an Amazon E2 rental) in about 10 minutes - no human interaction required.

Security is just an illusion.

No.

It is recommended procedure to configure appropriate security and set a password on a wireless access point. Unfortunately, this is not always done. Anyone within range could access such a network.

In other words it is possible to enter another person network by accident without realising it? Since as no security key is needed.

will you be prompted to select the type of network(home/public/work etc.) everytime you connect to a new network? To at least let the user know that they have click and tried to connect to a different network than usual.

Yes - it is possible to connect to the wrong wireless network without knowing it. If a 3rd party app controls the connection, it may be possible to make the connection to the strongest signal without any human involved.

When you pick a network type (home/work/public), there is an option to automatically make the same choice for all future connections. I've never selected that option, so I cannot tell you if the user sees anything when new networks are joined or not.

All connected network will be listed under the manage wireless connection right?

I would think so - but I don't have a computer to double check that. I usually don't keep 3rd party tools installed for wireless connection management.

I was checking the network and internet setting for someone when I spotted something I have never seen before in the network adapter. It's call 'microsoft virtual miniport adapter'. I did some research and it seems like a virtual network to allow others to connect to the network through the PC. Making it work like a hotspot.

I have immediately disabled it and am wondering whether disabling itit alone is sufficent to protect it from being use by other people? The user of the PC is someone who isn't very tech savy, so I am wondering is there a need for me to set even more things for her or is disabling the Microsoft virtual miniport adapter sufficent enough.

When I say disable it I mean through the network adapter where I right click it and click disabled NOT through the command prompt. Btw I don't think it's been properly set up since as under the sharing tab the allow others to connect is not tick.
