By storing the most time-sensitive virus information in the virus pattern file,
Trend Micro is able to minimize the number of scan
engine updates while at the same time keeping protection up-to-date. Nevertheless,
Trend Micro periodically makes new scan engine versions
available. New engines are released, for example, when:
-
Trend Micro has incorporated new scanning and detection technologies into the software
-
A new, potentially harmful, virus is discovered that cannot be handled by the current engine
-
Scanning performance is enhanced
-
Support is added for additional file formats, scripting languages, encoding, and/or compression formats
