ActiveUpdate is a function common to many Trend Micro products. Connected to the
Trend Micro update website, ActiveUpdate provides the latest downloads of virus pattern
files,
scan engines, and program files through the Internet. ActiveUpdate does not interrupt
network
services or require you to restart endpoints.
ActiveUpdate supports incremental updates of pattern files. Rather than downloading
the entire pattern file each time, ActiveUpdate can download only the portion of the
file that is
new, and append it to the existing pattern file. This efficient update method can
substantially
reduce bandwidth needed to update your antivirus software.
