## The Trend Micro Pattern Files

The Trend Micro scan engine uses an external data file, called the virus pattern file, to identify the latest security risks.
You can view the most current version, release date, and a list of all the new definitions included in the file from the following website:
http://www.trendmicro.com/download/pattern.asp
To view the version of the pattern file that ScanMail is currently using on your ScanMail server, open the product console and view Summary → System.

| ##### Tip Trend Micro recommends frequently updating your pattern files. Scheduled updates can be used to conveniently and regularly update ScanMail components.
