On-demand database scan
For each selected web site, its hierarchy of folders and files is scanned. Each file, user document or other SharePoint internal file is stored in a temporary file which is then sent to the kernel for scanning. If there are also older versions of a particular file and the Scan document versions feature is enabled, then the older versions are scanned first.
•Scan in read-only mode - infected documents will not be cleaned or deleted. The delete rule action will not be applied.
•Scan document versions - if other versions of the same document exist within the SharePoint database, these will also be scanned.
•On document delete restore the latest clean version - when an infected document is deleted, older non-infected versions are scanned. If older versions that are not infected exist, the most recent clean version will be restored and made the current version. This option is not available when Scan in read-only mode is enabled.
•Scan targets - a window will open where you can scan all targets or select your specific targets. For more information see On-demand database scan targets.
•Number of concurrent downloads - this parameter allows scanning in parallel by multiple threads. When set to 0, the legacy sequential processing is used.
