If you are afraid of being hacked or of having your computer invaded here's a PC tip from Digital Oracle.
If you use a firewall you can see what and whom is accessing your computer. Also if you are using a Windows NT based computer, such as NT4/2000/XP, there is another way of see who and what is connected to your computer, complete with location. This program is called netstat which you can access via the command prompt. Then just type netstat 10 and every 10 seconds you can see exactly what is connected to your computer. Very useful and ever more if u combine it with a tracer and a firewall. Anyway your choice.
