I've found that whenever I try to update the virus definitions for Norton Antivirus 2000 using the x86 Intelligent Updater package available from http://securityresponse.symantec.com/avcenter/download/pages/US-N95.html, I receive a message indicating the subscription is expired, though it is not expired. The error message I receive is as follows:
Symantec Security Response Intelligent Updater
Your virus protection cannot be updated.
Your subscription has expired. You must renew your subscription to continue using Intelligent Updater. Run LiveUpdate from Norton AntiVirus to renew your subscription and then run Intelligent Updater again.
Yet if I select Help, then About Norton Antivirus, and then click on the Norton AntiVirus tab, I see "Your virus definitions subscription started on 2/17/2004, and will expire in 210 days." I've tried this on several different occasions with similar results.
However, if I use the i32 Intelligent Updater package, which is available from the same URL, that package will update Norton AntiVirus 2000.
The i32 Intelligent Updater package, which is a smaller file than the x86 Intelligent Updater package, cannot be used to update Symantec AntiVirus Corporate Edition 8.0 servers or Norton AntiVirus Corporate Edition 7.6 servers, but can be used to update Corporate Edition clients. The x86 Intelligent Updater package can be used to update Corporate Edition clients and servers.
