In some circumstances, it might be necessary to update Security for SharePoint's .DAT files manually. For example, to respond quickly to an outbreak situation, a manual update of .DAT files might be required.
When you update DAT files manually, it is important to update the
DATVersion value in the
SystemState registry key. (This process is detailed in the Solution section below.) Security for SharePoint does not use the new DAT set if the registry is not updated to reflect the physical location for the new files.
The new .DAT files are loaded when Security for SharePoint scans the next item, such as a document or web part. Until the net scan occurs, the updated DAT information is not displayed in
Scanner Information in the Antivirus settings of the Antivirus and Content window.
