I'm connected to the Internet, but I can no longer access any websites. When I open Mozilla Firefox, I get the message "The connection was refused when attempting to contact www.(any site I try).com." Sometimes I get another message that says "The document contains no data." When I open IE, I get a message that "The page cannot be displayed." When I type in a website's URL, I get the message "Internet Explorer could not open the search page." I seem to be connected to the internet, though--for example, I was able to run Norton LiveUpdate. I have a cable modem, and I connect using wireless. I tried plugging in the cable, and it still didn't work, although it works fine on our desktop computer, which makes me think that the problem is not with our ISP. My IE firewall is off, and I tried disabling Norton Security but still couldn't load any websites. I cleared my caches; that didn't help either. I've tried plugging in the numbers for Google (to see if it's a DNS problem), but it still wouldn't load. I'm not very technologically savvy, and I'm at a loss about what to try next. Any suggestions would be greatly appreciated!!!
