[can't get google]

Your problem sounds very strange indeed. How are you connecting to the 
internet?

I think you should check that your dns is working:

$ host www.google.co.uk

gives me

www.google.co.uk is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 64.233.183.104
www.l.google.com has address 64.233.183.99
www.l.google.com has address 64.233.183.103
www.l.google.com has address 64.233.183.147


then
$ traceroute www.google.co.uk

[where I've elided some IP addresses and hostnames]

Does firefox work when you use the IP address above?
Does safari work?
