Sorry if I sound stupid
Being as novice as I am with the iternet, I have only learnt today that people can use my broadband connection if the have wireless connection on their PC / Laptop... (I found this out by a work collegue who does this)
I don't have wireless connections on my PC for the interent... Does this mean peolple can still hack my internet? She tells me I need a modem locker... Does anyone use one of these? If so does anyone recomend one (If I need one) 
Sounds like the typical secretary that can type letters and assumes she can also manage a network and handle computer hardware matters.
For someone to use your ADSL connection, they need an ADSL connection themselves, and they need to know your password/username you use to log in. All that will protect you from that will be common sense, and probably a reasonable firewall.
