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.

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.
