Trend Micro Apex One generates
significant network traffic when it updates a component. To reduce
network traffic generated during component updates, Trend Micro Apex One performs
component duplication. Instead of downloading an updated full pattern
file, Trend Micro Apex One only
downloads the "incremental" patterns (smaller versions of the full pattern
file) and merges them with the old pattern file after the download.
Security Agents updated
regularly only download the incremental pattern. Otherwise, they download the full
pattern file.
Trend Micro releases new pattern files regularly.
Trend Micro also releases a new pattern
file as soon as a damaging and actively circulating virus/malware is discovered.
