User`s guide

The URL filter will compare the links found in the e-mail against the links from the
BitDefender database of known spam links. In case of a match, the e-mail will be
considered SPAM.
The NeuNet (Heuristic) filter will take over the e-mail and will perform a set of tests
on all the message components, looking for words, phrases, links or other
characteristics of SPAM. Based on the results of the analysis, the e-mail will receive
a spam score.
Note
If the e-mail is tagged as SEXUALLY EXPLICIT in the subject line, BitDefender will
consider it SPAM.
The Bayesian filter module will further analyze the message, according to statistical
information regarding the rate at which specific words appear in messages classified
SPAM as compared to those declared NON-SPAM (by you or by the heuristic filter).
A Spam score will be added to the e-mail.
If the aggregate spam score (heuristic score + Bayesian score) exceeds the threshold
level, the e-mail is considered SPAM. The threshhold level is defined by the antispam
protection level. For more information, please refer to “Adjusting the Protection
Level” (p. 94).
18.1.3. Antispam Updates
Every time you perform an update:
● new image signatures will be added to the Image filter.
● new links will be added to the URL filter.
● new rules will be added to the NeuNet (Heuristic) filter.
This will help increase the effectiveness of your Antispam engine.
To protect you against spammers, BitDefender can perform automatic updates.
Keep the Automatic Update option enabled.
18.2. Antispam Optimization Wizard
The first time you run your mail client after you have installed BitDefender, a wizard
will appear helping you to configure the Friends list and the Spammers list and to
train the Bayesian filter in order to increase the efficiency of the Antispam filters.
Note
The wizard can also be launched any time you want by clicking the Wizard button
from the Antispam toolbar.
You can navigate through the wizard using the Next and Back buttons. If you want
to skip a configuration step, select Skip this step. To exit the wizard, click Cancel.
