See if you can access a problem site through a web based proxy

Problem solved, my AVG was about to expire so I removed it and installed Security Essentials, and now the problem seems to have gone

I hope you remove AVG properly,

Notice the IP addresses that resolve when you ping twitter, facebook, etc. Several of them have the same IP. It sounds to me like malware that has either planted a hosts file with this IP or tampered with your DNS settings.

That's just the first two things that come to mind. Check your network configuration. See if your DNS settings match the ones from the computers on your network that are indeed working.

Run (as administrator) ipconfig /flushdns

I don't think that will change anything, but it might. The entries may have a ridiculously long TTL.

Nothing else is jumping into my brain right now, so try that and keep us composted.
