Have problem reaching a website.

I am trying to reach myquiznos.com using vista and comodo free internet security. I can visit most of my other sites but this one it doesnt load, I used IE8 Firefox3 and chrome all with same results. Using another laptop without comodo but with Zonealarm, I can reach the site. The website support said change settings in the comodo but I dont know where or how.

Here is the error from chrome

You attempted to reach myquiznos.com, but instead you actually reached a server identifying itself as www.myquiznos.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of myquiznos.com. You should not proceed.

I don’t think this is a firewall related issue. What I get from the warning of Chrome is that there may be a cross scripted site exploit going on.

What happens when you use Chrome on the other laptop running ZoneAlarm?
