I have no idea what you are talking about...

Intercepted network? Like somebody sniffing your network?

Try to formulate again.

Yes, please clear that up a bit. Do you think someone is getting into your network, or intercepting your traffic? Get a good firewall to protect your network (there are free software based firewalls available.)

Do you mean your wireless network or did they break through your router/firewall and get into your network like that?
