5.4. Email Scanner for MS Exchange (VSAPI)
This item contains settings of the Email Scanner for MS Exchange (VSAPI).
The Basic Settings section contains the following options:
Enable component - uncheck to disable the whole component.
Language - select preferred component language.
The Scan settings section:
Background Scan - you can enable or disable the background scanning process here. Background
scanning is one of the features of the VSAPI 2.0/2.5 application interface. It provides threaded scanning
of the Exchange Messaging Databases. Whenever an item that has not been scanned with the latest
AVG virus base update is encountered in the users’ mailbox folders, it is submitted to AVG for
Exchange Server to be scanned. Scanning and searching for the not examined objects runs in parallel.
A specific low priority thread is used for each database, which guarantees other tasks (e.g. email
messages storage in the Microsoft Exchange database) are always carried out preferentially.
Proactive Scan (incoming messages)
You can enable or disable the proactive scanning function of VSAPI 2.0/2.5 here. This scanning occurs
when an item is delivered to a folder, but a request has not been made by a client.
As soon as messages are submitted to the Exchange store, they enter the global scanning queue as
low priority (maximum of 30 items). They are scanned on the first in, first out (FIFO) basis. If an item is
accessed while still in the queue, it is changed to high priority.
