Note
By default background scanning is disabled. You should enable it only as a second
layer of protection when you want to check all your databases and make sure they
are clean.
● Proactive scanning allows scanning messages before they are actually accessed.
When a message is submitted to the Store, it is placed in the global scanning queue
and assigned a low priority. If and when threads are available in the thread pool
and no high priority message remains to be scanned, each message in the global
scanning queue is submitted for scanning. On the other hand, if a message in the
global scanning queue is requested by a client, it is assigned a high priority and it
is removed from the low priority list.
Proactive scanning optimizes the overall scanning process because the messages
having undergone proactive scanning are not scanned again when accessed (unless
the virus stamp has changed in the meantime).
Note
By default, proactive scanning is enabled.
● Transport scanning prevents infected messages from entering Exchange mailboxes.
After entering the Exchange store, the messages are scanned before being
resubmitted to the transport engine which delivers them to their destination.
Messages are then scanned again on the back-end server.
Note
By default, transport scanning is enabled.
In order to configure proactive, background and transport scanning, open the
management console, go to the Antivirus module, Real time tab and click Advanced.
For more information, please refer to “Configuring Advanced Antivirus Settings” (p.
