Neighbours can see pc and internet contents with network discovery off

I would look for holes in the walls if they are seeing what you are doing .
Set your pc up with a strong password, this will stop most people from being able to remote into your pc, then setup your router to use the mac table and allow computers to access the router by thier mac, this way you can control which computers are allowed to access your network.
To find your pc mac open a command prompt (type cmd in search and run as admin) and then type ipconfig /all and enter, you will see a bunch of stuff listed, look for the "Physical Address" entry and you will see 6 set (12 numbers/letters; 00-B2-34-4C-DF-1A for example), this is your mac affress and what you will want to put into your routers mac table.

thanks guys, at the moment i am using the virgin super hub, the security settings are set to WPA Auto for the wireless settings so i will look into changing that, have changed the SSID and phasphrase always using upper and lower plus numbers. The problem is i never learned really how to use a computer or set one up just tried to guess it, so the blind has led the blind to this problem. You guys rock and Merry Christmas to you all have a good new year too :)

is it possible for someone to check out my screen shot and confirm that this pc is now set up for just 1 account only please

thank you Dwarf looks like i have fixed my pc problems then, before there was more than 1 set of the numbers you had described yet only 1 account set up on the pc, the problem was not network related via wpa is was when i was reinstalling my pc and remote desktop control settings was enabled for my pc to be controlled remotely i did not disable them then restart immediately and somehow my pc was being hacked by my neighbours. Cheers my man im a happy boy :) btw i noticed that the more than 1 number was on my desktop and my laptop, it was a similar number with 1001 at the end, also used the disable the built in admin just to make sure it was secure via cmd and net user admin/active:no after restarting and disabling remote services. I understand its disabled by default but better safe than sorry.
If the allow my pc to be controlled remotely and the remote asisstance tab is ticked is it possible for the pc to be hacked ?

After posting this thread its kind of comfirmed that you dont need to do anything to windows 7 for it to be setup securely right?
what else do you need to do to a new installation on a pc

Bur if there was another account number and i did not create it how on earth did it get there in the first place if its secure and using recommended settings?

Maybe i should let this post go now it seems as though it is fixed but as typical humans we all have a thirst to understand why and how and if from this post i can help other people then it has been a worthy lenghty cause :)

i only have the standard firewall that came with the pc, what would you recommend, it needs to be gamer friendly please and easy to use
