You can configure several realtime scan settings, including the following:
- The ability to scan documents on upload or
download
- The ability to download infected
documents
- The number of seconds the realtime scan
should run before timing out
You can use SharePoint Central Administration to configure these settings.
To access the settings-
In the SharePoint and WSS Antivirus Settings section of the Antimalware - Realtime pane, click the link to SharePoint Central Administration.
-
In the SharePoint Central Administration window, click the Operations tab, and then under Security Configuration, click Antivirus
-
In the Antivirus window, in the Antivirus Settings, Antivirus Time Out, and Antivirus Threads sections, you can change various settings, as described in the sections that follow.
Configuring antivirus settings
The Antivirus Settings section specifies when you want Microsoft Forefront Protection 2010 for SharePoint (FPSP) to scan the documents stored in document libraries and lists for viruses, as well as whether you want to attempt to clean infected documents. This section contains the following configurable settings:
- Scan documents on upload—Specifies
whether to scan a file that is being uploaded to the SharePoint
server. This setting is enabled by default.
- Scan documents on download— Specifies
whether to scan a file that is being downloaded from the SharePoint
server. This setting is enabled by default.
- Allow users to download infected
documents—If enabled, this setting permits the downloading of
documents known to be infected. If this setting is left disabled
(the default setting), FPSP blocks all known infected documents
from being downloaded.
- Attempt to clean infected documents—If
enabled, this setting permits the realtime scan to clean infected
documents, if possible. If the file cannot be cleaned, it is
reported as infected, and FPSP blocks the document from being
downloaded (unless the Allow users to download infected
documents setting is enabled). If the infected file is nested
and cannot be cleaned, the realtime scan removes the infected
nested file. If this setting is disabled, FPSP marks a detected
file as infected, makes no attempt to clean the file, and blocks
the file from being downloaded (unless the Allow users to
download infected documents setting is enabled). This setting
is enabled by default.
Configuring antivirus timeout
The Antivirus Time Out section permits you to modify how long, in seconds, the realtime scan should run before timing out. If server response time is slow while scanning, you may want to decrease the time. The default value is 600 seconds (10 minutes). This setting is displayed on the Forefront Protection 2010 for SharePoint Administrator Console as Timeout scanning after (seconds).
Configuring antivirus threads
The Antivirus Threads section permits you to modify the number of execution threads that the realtime scan can use. If server response time is slow while scanning, you may want to decrease the number of threads allowed for virus scanning. The default value is 10 threads. This setting is displayed on the FPSP Administrator Console as Allow scanner to use up to (threads).
