8.6. E-mail Scanner
One of the most common sources of viruses and trojans is via e-mail. Phishing and
spam make e-mail an even greater source of risks. Free e-mail accounts are more likely
to receive such malicious e-mails (
as they rarely employ anti-spam technology
), and
home users rely quite heavily on such e-mail. Also home users, surfing unknown sites
and filling in online forms with personal data (
such as their e-mail address
) increase
exposure to attacks via e-mail. Companies usually use corporate e-mail accounts and
employ anti-spam filters etc, to reduce the risk.
8.6.1. E-mail Scanner Principles
Personal E-mail Scanner
scans incoming/outgoing e-mails automatically. You can use
it with e-mail clients that do not have their own plug-in in AVG (
but can be also used
to scan e-mail messages for e-mail clients that AVG supports with a specific plug-in, i.
e. Microsoft Outlook, and The Bat
). Primarily, it is to be used with e-mail applications
like Outlook Express, Mozilla, Incredimail, etc.
During AVG
installation
AVG there are automatic servers created for e-mail control:
one for checking incoming e-mails and the second one for checking outgoing e-mails.
Using these two servers e-mails are automatically checked on ports 110 and 25 (
standard ports for sending/receiving e-mails
).
E-mail Scanner
works as an interface between e-mail client and e-mail servers on the
Internet.
·
Incoming mail:
While receiving a message from the server, the
Scanner
component tests it for viruses, removes infected attachments, and
adds certification. When detected, viruses are quarantined in
Virus Vault
immediately. Then the message is passed to the e-mail client.
·
Outgoing mail:
Message is sent from e-mail client to E-mail Scanner; it tests
the message and its attachments for viruses and then sends the message to
the SMTP server (
scanning of outgoing e-mails is disabled by default, and can
be set up manually
).
Note:
AVG E-mail Scanner is not intended for server platforms!
