2. When will I receive the patch?

As is our standard practice, we are deploying the patch in a phased manner. We have released the patch to randomly selected customers, and will then monitor our telemetry, as well as this forum, for any problems or issues.  Once we have confirmed the effectiveness of the patch, we will make it available to all customers. We will post an update on the Norton Community Forums when we make the patch available to all customers.
If you have Google Chrome installed, this patch will require receiving a Chrome extension update, which is now released for all Norton 21.6 customers in chrome store.  Once the Chrome extension named “Norton Security Toolbar” has been updated to version 2014.7.8.25, then this patch may be applied via Live Update.

This patch is only available via LiveUpdate, and is being released in a phased manner.

4. I see the engine for this version on my system, but my product hasn't updated. What's wrong?

Nothing is wrong; that's how our updates are distributed for the phased approach. The update comes in two parts, and most people will get the engine. Both parts together will get your product updated.
