8.5. 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.
8.5.1. 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 E-mail
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!
