Pinging General Failure after uninstalling Norton

My machine has Vista installed and Norton as anti virus and for internet security.
I just remove Norton by using Uninstall in Vista's Control Panel and could not found
any uninstallation program that come with it.
The anti virus has gone, but two Live Update still reside as Service and one service named like Symantec Application ... ( I forgot the complete name). They could not be uninstalled. I leave them as is, than try to work with my local web with results:

- My local web could not be reach.
- Try with three kinds of different software databases to test local connection, no success.
- Try a ping command to domain name, even localhost or 127.0.0.1, come with General Failure reply.
- As administrator try to reset winsock and IPv4:
C:\Windows\System32>netsh winsock reset catalog
C:\Windows\System32>netsh int ipv4 reset reset.log
C:\Windows\System32>netsh int ipv6 reset reset.log
restart the machine, still General Failure.

Then I arrived here and use it to completely remove Norton software.
It works again.
