About updating virus definitions

Symantec Message Filter relies on up-to-date information to detect viruses and threats. One of the most common reasons that problems occur is that virus definition files are not up-to-date. Symantec regularly supplies the updated virus definition files that contain the necessary information about all newly discovered viruses and threats. Regular updates of virus definitions maximize security and guard your organization against infections and the downtime that is associated with an outbreak.

The Brightmail LiveUpdate service on Windows platform and jlu-controller daemon on Solaris and Linux platforms are used to update antivirus definitions on Symantec Message Filter.

LiveUpdate downloads and installs available definitions to update your protection.

See Obtaining the virus definition updates.

Rapid Release

Rapid Release definitions are more frequently updated than the LiveUpdate definitions. These definitions can be used when you need quick response to emerging threats. Rapid Response is an alternative to LiveUpdate.

See Obtaining definitions when a new or emerging threat is discovered

You must have a valid content license to install definition files. A content license is a grant by Symantec Corporation for you to update Symantec corporate software with the latest associated content, such as new definitions. When you do not have a content license or your license expires, your product does not receive the most current definitions. Your environment is vulnerable to attacks.
