Thanks syphus. Recently I did XP-No-Reformat on my pc, I believethe process did change the registry value and deleted the Norton's subscription period. So now I had changed the anti virus to Avast! Home Addition v4.7.
Base on the few views from other site, we are recommended to install a extra Fire Wall. I know Norton has Fire Wall itself, which is Internet Worm Protection if I didn't wrong. So I wonder what's sphus's opinion against my case.
