I am an AVG fan myself. It has a smaller footprint on the hd and ram - updates are easily scheduled or handled manually and you gotta love the price-tag.

Sgear, you can also d/l the signatures via FTP by going to ftp.symantec.com then navigate through the public/english_us_canada/antivirus_definitions/norton_antivirus and download the current *-x86.exe file and all should be well. As for why your system is not updating - who knows? How old is the software? Did your license possibly expire? If you are trying to run LiveUpdate are you behind a proxy? Is your firewall blocking you? Is the config correct and pointing to the Symantec LiveUpdate site?

You can also check the knowledge base (under support) for the problems you are having and may find a workable solution fairly soon.
