The Security Server includes a service called Scan Server,
which is automatically installed during Security Server installation.
As such, there is no need to install it separately. The Scan Server
runs under the process name iCRCService.exe and appears
as Trend Micro Smart Scan Service from Microsoft Management Console.
When Security Agents use a scan method called smart scan,
the Scan Server helps these agents run scans more efficiently. The
smart scan process can be described as follows:
The Security Agent scans the client for security threats
using the Smart Scan Agent Pattern, a lightweight version
of the traditional Virus Pattern. The Smart Scan Agent Pattern holds
most of the threat signatures available on the Virus Pattern.
A Security Agent that cannot determine the risk of the file
during the scan verifies the risk by sending a scan query to the
Scan Server. The Scan Server verifies the risk using the Smart
Scan Pattern, which holds the threat signatures not available
on the Smart Scan Agent Pattern.
The Security Agent "caches" the scan query result provided
by the Scan Server to improve the scan performance.
By hosting some of the threat definitions, the Scan Server helps
reduce the Security Agents’ bandwidth consumption when downloading
components. Instead of downloading the Virus Pattern, Security Agents
download the Smart Scan Agent Pattern, which is significantly smaller
When Security Agents are unable to connect to the Scan Server,
they send scan queries to the Trend Micro Smart Protection Network,
which has the same function as the Scan Server.
It is not possible to uninstall the Scan Server separately from
the Security Server. If you do not want to use the Scan Server:
On the Security Server computer, open Microsoft Management
Console and disable the Trend Micro Smart Scan Service.
On the web console, switch Security Agents to conventional
scan by navigating to Disable Smart Scan Service.
and selecting the option
