Real-time scanning occurs whenever a file is saved to a SharePoint server
(check-in) or retrieved from the SharePoint server (check-out). Manual scanning scans
the
SharePoint content database and occurs immediately after you manually choose Scan
Now. Scheduled scans perform the same function as manual scans, but occur according
to the schedule you set. The duration of the scan depends on the number of files and
your
hardware resources.
To optimize the performance of your SharePoint environment, Trend Micro recommends that you NOT perform a manual or
scheduled scan during peak usage periods.

Note
When real-time scan is enabled and scan documents on download and scan
documents on upload are also enabled on the SharePoint Anti-Virus options, then, PortalProtect will scan the files while uploading,
but will not scan the files while downloading. Since these files have already been
scanned, PortalProtect will not scan them again
during download. This is due to limitations of Microsoft SharePoint.

Tip
Refer to the Online Help for specific information about how to use the PortalProtect Management console to configure and
perform scans.
|
PortalProtect secures your SharePoint
environment by performing scans on all content that is either uploaded or downloaded.
You can
configure PortalProtect to run scans on-demand
(manual scanning), according to a schedule (scheduled scanning), or in an ongoing
and persistent
manner (real-time scanning). Additionally, you configure scans using the Security
Risk Scan
screen, accessible from the sidebar, or from the Manual Scan and Scheduled
Scan screens.
|
Note
Real-time Scanning protects your SharePoint environment in an ongoing manner. When
you enable
real-time scan, it continually runs in the background. You can configure only one
real-time scan
at a time.
|
 |
WARNING
Trend Micro recommends that you always keep
real-time scan enabled. However, if you must disable the real-time scan functionality,
be sure
to run regular manual scans.
