Configuring the scheduled scan


Applies to: Forefront Protection 2010 for SharePoint

Topic Last Modified: 2010-02-08

There are various configuration settings that you can adjust for the Microsoft Forefront Protection 2010 for SharePoint (FPSP) scheduled scan in order to meet the needs of your environment. These include selecting the number of scan engines to use for each scan, setting the action to take when malware is found, and specifying whether or not to quarantine detected files.

To configure the scheduled scan
  1. In the Forefront Protection 2010 for SharePoint Administrator Console, click Policy Management and in Antimalware, click Scheduled.

  2. In the Antimalware - Scheduled pane, in the General settings section, configure the following setting:

    • Enable scheduled antivirus scan—Select or clear this check box to enable or disable the scheduled antivirus scan. This setting is enabled by default.

  3. In the Antimalware - Scheduled pane, in the Engines and performance section, select the number of scan engines that should be used for this scan. For more information, see Configuring the number of scan engines used for each scan.

  4. In the Antimalware - Scheduled pane, in the Scan actions section, configure the following settings:

    1. Action—Select the action that you want performed when malware is detected. For more information, see Configuring the action when malware is detected.

    2. Quarantine Files—Using the drop-down list, enable (by selecting Yes) or disable (by selecting No) saving infected files detected by the file-scanning engines. Quarantining is enabled by default. Enabling quarantine causes deleted files to be stored in a secure location, from which you can recover them. For more information about quarantine, see Viewing and managing quarantine.

    3. Edit Malware Deletion Text—You can specify Deletion text, which is used to replace the contents of an infected file during a delete operation. The default deletion text informs you that an infected file was removed, along with the name of the file and the name of the malware found. To change the default text, click Edit Deletion Text, make the modifications to the deletion text in the Edit Malware Deletion Text dialog box, and then click OK to return to the Antimalware - Scheduled pane.

      FPSP provides keywords that can be used in the deletion text field to obtain information from the message in which the infection was found. To use them, in the Malware Deletion Text dialog box, right click, select Insert Field, and then select the desired macro. For more information about this feature, see Keyword substitution macros.
  5. Click Save.

You can configure the following additional settings located under the Additional options section of the Antimalware - Scheduled pane. Click Save after making any changes to your settings.

  • Scan doc files as containers—Configures the scheduled scan to scan files that use structured storage and the OLE embedded data format (for example, .doc, .xls, .ppt, and .shs) as container files. This ensures that any embedded files are scanned as potential malware carriers. This setting is enabled by default.

  • Suppress malware notifications—Suppresses the sending of Virus found notifications even if this notification is enabled. This setting is disabled by default.

  • Set priority—Sets the CPU priority in order to permit more important jobs to take precedence over scheduled scans when demands on server resources are high. In the Set priority drop-down list, click one of the following: Normal (the default), Below normal, or Low.

  • Maximum container scan time (seconds)—Configures the number of seconds that the scheduled scan scans a compressed file before reporting it as a "ScanTimeExceeded" incident. This option is intended to prevent the risk of denial of service due to zip-of-death attacks. The default value is 600 seconds (10 minutes).

The Schedule options are described in Scheduling the scheduled scan. The Scan targets options are described in Selecting the sites to scan with the scheduled scan.
