For the last month, I have be getting attempted portscans from following address: hn.kd.ny.adsl. Fortunately the firewall is doing its job, but unfortunately everytime this address attempts to hit my computer I get a pop up and everything on my computer comes to a stop or slows way down for 30-60 seconds. Because it is not a numerical IP address, I am not been able to enter it in the addresses for the firewall to auto block as I have with many other addresses to solve the problem. I have checked this address and it appears to originate out of China and there are many complaints on the internet with this address also scanning many other computers. Sometimes this address will hit me several times while I am on the computer. What can I do so I don't have to deal with the pop ups and slow downs every times the portscan attempts occurring from this particular address and yet the Norton firewall is still doing its job?
