Figure 25. Selecting an email security level
By default, the email security level is set to Recommended.
You can raise or lower the email security level by selecting the level you want, or
editing the settings for the current level.
To change the security level:
Adjust the sliders. By altering the security level, you define the ratio of
scan speed to the total number of objects scanned: the fewer email
objects are scanned for dangerous objects, the higher the scan speed.
If none of the preinstalled levels fully meet your requirements, their settings may
be customized. It is recommended that you select a level closest to your
requirements as basis and edit its parameters. This will change the name of the
security level to Custom. Let us look at an example when preconfigured security
level settings may need to be modified.
Example:
Your computer is outside the local area network and uses a dial-up
Internet connection. You use Microsoft Outlook Express as an email client
for receiving and sending email, and you use a free email service. For a
number of reasons, your email contains archived attachments. How do
you maximally protect your computer from infection through email?
Tip for selecting a level:
By analyzing your situation, one can conclude that you are at a high risk
of infection through email in the scenario outlined, because there is no
centralized email protection and through using a dial-up connection.
You are advised to use Maximum Protection as your starting point, with
the following changes: reduce the scan time for attachments to, for
example, 1-2 minutes. The majority of archived attachments will be
scanned for viruses and the processing speed will not be seriously
slowed.
