4.2.2 Scanning in the Information Store
In addition to virus scanning at transport level, Avira AntiVir Exchange is also able to
scan data in the public or private MS Exchange Information Store.
There are three basic types of Information Store scanning:
•
On-Demand scan
When a client tries to open a mail, a comparison is performed to ensure that text
body and attachment have been checked by the current virus signature file. If they
have not, the message is scanned before being forwarded to the client. On-demand
scanning is the most commonly used task for Information Store scanning.
•
Pro-active scan
The proactive scan catches new messages before these are accessed by a client
through an on-demand scan. Used in addition to on-demand scanning, it can help to
speed up client access.
•
Background scan
A background scan checks all elements of the Information Store. It can be activated
separately for the public and private Information Stores and scans all elements that
were not yet scanned with the current scanner signature file.
In addition to a scheduled execution, the background scan is run whenever the database
is loaded (for example when a server is started).
The Information Store scan is a global function that applies to the entire server, so that
only one AntiVir Information Store scan job exists on each server (as opposed to any
number of virus scanning jobs).
If a virus is found in a mail, various actions tailored to the Information Store scan can be
performed:
•
block object
Object blocking denies access to the entire message object. Current Microsoft mail
clients generate a message when the user tries to open a blocked message, while
other and older clients may respond differently. The blocked message can always
