Table of Contents

The Basic Settings section contains the following options:

Enable component - uncheck to disable the whole component.

Language - select preferred component language.

The Logging settings section:

Log file size - choose a preferred size of the log file. Default value: 100 MB.

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 2007 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. e-mail 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.

Note: Overflow messages will continue to the store unscanned.

Note: Even if you disable both Background Scan and Proactive Scan options, the on

access scanner will be still active when an user will try to download a message with

the MS Outlook client.

Scan RTF - you can specify here, whether the RTF file type should be scanned

or not.

Number of Scanning Threads - the scanning process is threaded by default to

increase the overall scanning performance by a certain level of parallelism. You

can change the threads count here.

The default number of threads is computed as 2 times the

'number_of_processors' + 1.
