Configuring Scanning - Trend Micro? Online Help

Introducing Trend Micro ScanMail for Microsoft Exchange
Configure ScanMail to use ActiveUpdate and incremental updates to decrease the time
spent updating.
Using ActiveUpdate with ScanMail
You can configure ScanMail to use the ActiveUpdate server as a source for manual and
scheduled component updates. When it is time for the component update, ScanMail
polls the ActiveUpdate server directly. ActiveUpdate determines if an update is available,
and ScanMail downloads the updates if they are available.
Tip: For a more efficient download in a multi-server environment, configure ScanMail to
allow other servers to download updates from it. This makes ScanMail a virtual
ActiveUpdate server for other servers in your environment that receive incremental
updates.
About Trend Micro IntelliScan
IntelliScan optimizes performance by examining file headers using true file type
recognition and scanning only file types known to potentially harbor malicious code.
True file type recognition helps identify malicious code that can be disguised by using a
harmless file extension type. The following are just a couple of the benefits IntelliScan
offers to administrators:
• Performance optimization: Server system resources allotted to scan will be
minimal. Using IntelliScan will not interfere with other crucial applications running
on the server.
• Time saving: Since IntelliScan uses true file type identification, the scan time for
running IntelliScan is significantly less than the time required for all attachment files.
This means that only files with a greater risk of being infected are scanned. This
time difference is noticeable when you use IntelliScan with Manual scan.
