Unknown connector between my PC and router

I have an unknown icon between my pc and router in my network map. It is a secure net work. Also, I hear other people's conversation, music, background noise like someone is connected to me computer remotely. Someone please help it's freaking me out!!!

Unplug your computer from your router at your computer's network card. Do you still hear the conversations, music, background noise? Or do you have a wireless network card and that's why you included the word secure?

Yes I have a wireless connection. I have no clue what you mean network card lol. I included the word secure because I thought it might make a difference.

OK, turn off the wireless networking either at the router (unplug the router) or at your computer (laptop?) and then check and see if you can still hear the background noise. I'm guessing your laptop will have a switch that will turn off the power to your wireless adapter.
