The Bayesian filter is also utilized in filtering. By marking messages
as spam and not spam, the user creates a database of words used in
each of these respective categories. The larger the database, the more
accurate the results it yields.
A combination of the above‑mentioned methods provides a high
Antispam detection rate.
ESET Smart Security supports Antispam protection for Microsoft
Outlook, Outlook Express and Windows Mail.
4.3.1 Self‑learning Antispam
Self‑learning of Antispam is related to the previously mentioned
Bayesian filter. The importance of individual words changes during
the “learning” process of marking individual messages as spam or not
spam. Accordingly, the more messages that are classified (marked as
spam or not spam), the more accurate the results obtained with the
Bayesian filter will be.
Add known addresses to the whitelist to exclude messages from these
addresses from filtering.
4.3.1.1 Adding addresses to Whitelist
Email addresses belonging to people whom the user communicates
with frequently can be added to the list of “safe” addresses (Whitelist).
Doing so ensures that no message originating from a whitelist address
is ever classified as spam. To add a new address to the whitelist,
right‑click on the given email message and select Add to Whitelist
under the ESET Smart Security context menu option, or click Trusted
address in the ESET Smart Security Antispam toolbar in the upper
section of your email program. Similarly, this process applies to spam
addresses. If an email address is listed on the blacklist, each email
message which arrives from that address is classified as spam.
4.3.1.2 Marking messages as spam
Any message viewed in your email client can be marked as spam. To
do so, use the context menu (right‑click) and then click ESET Smart
Security > Reclassify selected messages as spam) or click Spam
from the ESET Smart Security Antispam toolbar located in your email
client.
Reclassified messages are automatically moved to the SPAM folder,
but the sender email address is not added to blacklist. Similarly,
messages can be classified as “not spam”. If messages from the
Junk E‑mail folder are classified as not spam, they are moved to
their original folder. Marking a message as not spam does not
automatically add the sender address to the Whitelist.
4.4 Updating the program
Regular updating of the system is the basic premise for obtaining
the maximum level of security provided by ESET Smart Security.
The Update module ensures that the program is always up to date.
This is done in two ways – by updating the virus signature database
and by updating all system components.
Information about the current update status can be found by clicking
Update, including the current version of the virus signature database
and whether an update is required. In addition, the option to activate
the update process immediately – Update virus signature database
– is available, as well as basic update setup options such as the user
name and password to access ESET’s update servers.
The information window also contains details such as the date
and time of the last successful update and the number of the virus
signature database. This numeric indication is an active link to ESET’s
web site, listing all signatures added within the given update.
NOTE: The User name and Password is provided by ESET after
purchase of ESET Smart Security.
4.4.1 Update setup
The update setup section specifies the update source information,
such as the update servers and authentication data for these servers.
By default, the Update server: field is set to Choose automatically.
This value ensures that the update files will automatically be
downloaded from the ESET server with the least network trac load.
The update setup options are available from the Advanced Setup (F5)
tree, under Update.
