Can't Update Norton

Having been 'cleaned up' thanks to help from this forum I think I have another virus as I can't update my Norton Antivirus software using LiveUpdate.

Could someone tell me if I have another virus and how to get rid if I have?  I have run SpyBot and Ad-Ware.

Thanks in advance!
