Symantec has started delivering automatic product updates, previously, updates were only delivered via the annual release of new product versions.

Users of Norton Internet Security 2006, Norton AntiVirus 2006, Norton SystemWorks 2006, Symantec AntiVirus Corporate Edition 10.0 and Symantec Client Security 3.0 got an update to their anti-virus scanning engine through LiveUpdate in December. Users were also notified of a critical update and asked to manually download a new spyware blocking tool.

LiveUpdate is a feature of many Symantec products and automatically downloads updates to protect users against the latest threats.

Symantec said it decided to start pushing out product updates in order to keep up with the evolving threat environment.

The new scanning engine works when the operating system boots up, protecting against malicious code that hides from typical scanning methods. The new spyware tool blocks spyware and adware applications from being installed on users' computers.
