On my laptop i have a weird problem, none of my web browsers can access the internet.
But msn messenger and Thunderbird are perfectly working. I have a wireless broadband connection. My guess is some viruses may block my port:80.

I would suggest checking your DNS. Open command prompt and try to ping, if that doesn't work try pinging, which is a IP. If it doesn't work for the address, but it does for the IP, you probably have a DNS issue.

You could try to manually set your DNS to something new like which is google's new DNS, or (not google)
