By storing the most time-sensitive virus/malware information
in the virus patterns, Trend Micro minimizes
the number of scan engine updates while keeping protection up-to-date.
Nevertheless, Trend Micro periodically
makes new scan engine versions available. Trend Micro releases new
engines under the following circumstances:
-
Incorporation of new scanning and detection technologies
into the software
-
Discovery of a new, potentially harmful virus/malware that
the scan engine cannot handle
-
Enhancement of the scanning performance
-
Addition of file formats, scripting languages, encoding,
and/or compression formats
