Which version of Word? Unless you intend to pay for the full version of Norton, scrap it and get a free antivirus program. AVG or Avast are used by many forum members click here. Uninstaller for Norton - click here use it offline, and after downloading alternative anti-virus software, don't install free AV without removing Norton first.
You can get a firewall and a couple of anti-spyware apps from the first site I linked to as well (all free).
