Norton AntiVirus 11.1/Internet Security 4.1 update available

An update to Norton Internet Security 4.1/Norton AntiVirus 11.1 is now available. Among the improvements made in this update:

  • Norton Internet Security and Norton AntiVirus are fully compatible with the 64-bit kernel environment. You are fully protected when booted into 64-bit kernel mode. The applications in Norton Internet Security and Norton AntiVirus are still 32-bit however.
  • Some minor issues in Norton Firewall have been fixed.
  • A new Vulnerability Protection engine is included, which addresses some bugs and also improves performance & security.

This update is available to all Norton customers who have a valid subscription, including Comcast subscribers.

Note that some users may need to run LiveUpdate twice in order to receive all the available updates. If you choose to update manually & immediately, please run LiveUpdate multiple times, until it says "Already up to date" for all the items in the list. Also note that due to replication delays, this update will take several hours to become fully available to all customers. If you don't see any updates available, please wait a couple of hours and try again.
