My Mac won't load certain pages

[AshtonDmau5]

I've changed the DNS and done instructions from other forums,
To no result.
The sites that won't load are Facebook, Twitter, YouTube, Apple site & eBay.
I have installed flash & java correctly, and it won't work.
I do not have peer guardian, and my proxies & firewalls are not the problem

Please help?

If your proxies aren't the problem, then it has to be DNS.

Try OpenDNS if you haven't already (i.e. set your default DNS server on your router and/or Mac to 208.67.222.222)

Nope, already had that on,
Still not working.

Can you resolve their IP addresses in Terminal, using nslookup or something similar?

Have you tried multiple browsers, like Firefox or Chrome in addition to Safari?

More details please. Which, Mac, what version OS, and what's the last change you made?

Cheers,

MacBook, 13", 10.5.8, I got iLife 09', but it has been a problem for a few weeks.
I have tried them on the PC, works fine.
On my MacBook, I have used Safari, Chrome & Firefox.
I have 'iAntiVirus' installed, and have searched many times, but no virus' have been found.

I have 'iAntiVirus' installed, and have searched many times, but no virus' have been found.

That's because there are no Mac viruses in the wild. Try uninstalling iAntiVirus and rebooting. See if that fixes it.

Otherwise, my suggestion is to make a new location profile in the Network control panel and add back your interface and, if applicable, your wifi network.

It sounds like there's a problem with your hosts file on your Mac, though I don't know enough about it to give advice on how to fix it.
