There is only one website that I can't access. It is english.aljazeera.net. I can't even ping it when every one I know can. Its ip address is 12.120.9.19. I hooked up another computer to my modem to the cable outlet and I was able to access this website from the other computer and ping it too. My cable company are saying it is for sure a computer problem (obviously) and Dell are saying it is a firewall problem. However, since I don't have any firewall programs they blamed the Mcafee firewall that I uninstalled. They say it sometimes leaves blockage after unintallation. I removed all Mcafee files and keys from the registry but still can't find the problem. I'm afraid my computer in infected.
