Go to Personal Firewall on your computer and select "Configure"I did a google search on the problem and it appears to be a problem with Norton Security. You can try to update your version of Norton Internet Security if you know how. You then still have to add www.haloscan.com as a "trusted site"
Select "Networking" tab.
Select "add" and enter www.haloscan.com as a "trusted site".
I also found some people are saying that they use AVG instead of Norton.
