Can't connect with Internect Explorer 7 or with Firefox 2. Please help.?

When I try to use IE, I get the "Internet Explorer cannot display webpage" message. Similar thing happens with Firefox 2. HOWEVER, an older version of Firefox works just fine. Can anyone tell me why this is and how to fix it?

Windows Vista Home Basic, HP laptop

My Windows firewall is disabled and I am using Symantec Antivirus 10.2. I've scanned my computer several times (with different programs as well) and found nothing.

I've used a wireless connection pretty exclusively, and have run into the same problems in different locations.

On Firefox, click Tools %26gt; Options %26gt; Advanced %26gt; Network %26gt; Settings.

And then make sure the 'direct connection to internet is selected'. +Symantec is rubbish.

I'm pretty sure Vista comes with Windows Defender, I'd advise you to use that, or try Avast, NOD32, AVG, or Kaspersky.
