Configuring Scheduled Scans

Trend Micro recommends that you do not schedule a scan at the same time as a scheduled update. This may cause the Scheduled Scan to stop prematurely. Similarly, if you begin a Manual Scan when a Scheduled Scan is running, the scan stops, but will run again according to its schedule.

  1. Navigate to Scans > Scheduled Scan.
  2. Click the Schedule tab.
    1. Configure the scan frequency (daily, weekly, or monthly) and start time. Each group or Messaging Security Agent can have its own schedule.

      For monthly Scheduled Scans, if you select 31, 30, or 29 days and a month has less than the number of days, the scan will not run that month.

    2. (Optional) Select Shut down the client after completing a Scheduled Scan.
    3. Click Save.
  3. (Optional) Click the Settings tab to customize Scheduled Scan settings.

    To customize scan settings for the Messaging Security Agent, expand an agent and click the following:

    • The agent performs a scan every Sunday, starting at 5:00 AM.

    • Customize this schedule to run during an off-peak time for your clients. The agent scans all scannable files. It includes the message bodies of email messages in the scan.

    • When the agent detects a file with a virus or other malware, it cleans the file. When it cannot clean the file, it replaces with text/file instead.

    • When the agent detects a file with a Trojan or worm, it replaces the Trojan or worm with a text/file.

    • When the agent detects a file with a Packer, it replaces it with text/file.

    • The agent does not clean infected compressed files.

  4. Select the groups or Messaging Security Agents that will apply the Scheduled Scan settings.
