Setting up a wireless connection

I setup a wireless connection on a new computer then using a wireless USB adaptor I set up my other computer.
During this setup I received a message listing other connections in my area that could read my messages what can I do about this?
It also stated the I had an unsecure network what does this mean?

Thanks for any replies.

Have a good read of this, then set up WPA2 with a strong passphrase:
