root domain icon, choose from the following options:
• Apply to All Clients: Applies settings to all existing clients and to any new
client added to an existing/future domain. Future domains are domains not yet
created at the time you configured the settings.
• Apply to Future Domains Only: Applies settings only to clients added to
future domains. This option will not apply settings to new clients added to an
existing domain.
Cache Settings for Scans
The OfficeScan client can build the digital signature and on-demand scan cache files to
improve its scan performance. When an on-demand scan runs, the client first checks the
digital signature cache file and then the on-demand scan cache file for files to exclude
from the scan. Scanning time is reduced if a large number of files are excluded from the
scan.
Digital Signature Cache
The digital signature cache file is used during Manual Scan, Scheduled Scan, and Scan
Now. Clients do not scan files whose caches have been added to the digital signature
cache file.
The OfficeScan client uses the same Digital Signature Pattern used for Behavior
Monitoring to build the digital signature cache file. The Digital Signature Pattern
contains a list of files that Trend Micro considers trustworthy and therefore can be
excluded from scans.
Note: Behavior Monitoring is automatically disabled on Windows server platforms and
cannot be used on 64-bit platforms. If the digital signature cache is enabled, clients on
these platforms download the Digital Signature Pattern for use in the cache and do
not download the other Behavior Monitoring components.
