Hello to all,
I was concerned about the security and bandwidth usage
in my intranet.
The netstat -anW command gives me following output:

It can bee seen that yahoo servers have established
contact with my NIC (192.168.1.14]. Why so? Is it
valid? Or is Yahoo using my bandwidth? At least one of
the foreign addresses that have established contact
with my NIC is that of Yahoo?
How do I avoid it?
Please advise. TIA.
