Procedure

1. Go to Policy → Smart Protection.
   The Security Risk Scan tab appears by default.
2. Select one of the following malware scanning methods.
   • Conventional Scan: Conventional scan leverages anti-malware and antispyware components stored locally.
     The Virus Pattern contains information that helps IMSS identify the latest virus/malware and mixed threat attacks. Trend Micro creates and releases new versions of the Virus Pattern several times a week, and any time after the discovery of a particularly damaging virus/malware.
   • Smart Scan - File Reputation Services: Smart Scan leverages threat signatures that are stored in the cloud.
     When in Smart Scan mode, IMSS uses the Smart Scan Agent Pattern to check for security risks. The Smart Scan Agent Pattern is updated daily by Trend Micro and delivers the same protection provided by conventional anti-malware and antispyware patterns. If the Smart Scan Agent Pattern cannot determine the reputation of a file, IMSS queries the Smart Protection Network to provide up-to-date protection.

   Note Conventional Scan is the default scan method.

3. If you selected Smart Scan - File Reputation Services, select one of the following smart protection sources:
   • Smart Protection Network: If you select this option, specify the proxy server setting.
   • Smart Protection Server: If you select this option, click the Local Sources tab and configure Smart Protection Servers.

   Note IMSS reverts to Conventional Scan when the selected Smart Protection Network or Smart Protection Server is unavailable. IMSS can switch to Conventional Scan only when you have selected Switch to Conventional Scan when Smart Protection Network or Smart Protection Server is unavailable.

4. Click Save.

   Note If Smart Scan is selected, IMSS attempts to connect to the Smart Protection Network or Smart Protection Server immediately after you click Save. If a connection is not established, IMSS does not save your settings. Reselect a scan method and save your settings again. IMSS automatically restarts the Scan Service whenever you change your scan method settings.
