On-access scanning (AMON)
This is when you attempt to open a le and NOD32
will automatically check it for you rst via AMON (the
Access MONitor). By default, AMON will be the resident
scanner on your machine, always vigilant, always in the
background, always ready to warn you of an inltration.
On-access scanning (DMON)
DMON is a plug-in for NOD32 that serves for scanning
Microsoft Ofce documents and les downloaded
automatically by Internet Explorer (e.g. Microsoft
ActiveX elements). DMON provides an additional level
of protection to AMON.
Email scanning (EMON)
EMON (Email MONitor), a complementary resident
module, scans emails incoming via MAPI interface.
The MAPI interface exploits the different interfaces of
Microsoft Outlook. MAPI interface is used also when
receiving emails from the Microsoft Exchange Mail
Server via the Exchange protocol.
Internet trafc scanning (IMON)
IMON will also continually work in the background on
your machine, checking your incoming email and also
any websites that you visit and download from.
For more information on AMON, DMON, EMON & IMON or
the NOD32 scanner, please check the Help button in the
NOD32 Control Centre (there is a 2nd button in the right-
hand window too for specic module help) and/or have a
look through the Frequently Asked Questions (FAQ’s) on
the ESET website: http://www.ESET.com/support/faq.php
On access scanners load into system memory, and intercept all the calls
made by the operating system to the le system. In this way they ensure
that a le has been scanned before it is passed to the system for opening,
thus preventing a virus from infecting the sytem.
