About protection updates
Protection updates are files available from Symantec, by subscription, that
keep your Symantec products up-to-date with the latest anti-threat
technology. The protection updates you receive depend on which product
you are using.
About your subscription
See “Subscription
policy” on
page 142.
Your Symantec product includes a complimentary, limited-time
subscription to protection updates for the subscription services that are
used by your product. When the subscription is due to expire, you are
prompted to renew your subscription.
If you do not renew your subscription, you can still use LiveUpdate to
obtain program updates. However, you cannot obtain protection updates
and will not be protected against newly discovered threats.
