To sdcomm:
If your AV product really is NORTON Antivirus Corporate Edition and the version is 7.anything, you may as well not have anything installed at all. Completely unsupported and totally useless in today's threat environment. Even if the client was Symantec Antivirus Corporate Edition 10.1.x, as previously mentioned, it has reached end-of-life and is no longer supported.
If you still have a valid support contract, you can install SEP 11.0.7300 or SEP 12.1.2100
