NOD32 Architecture - advanced engineering provides enhanced protection!
Unlike the competition, the architecture of ESET NOD32
Antivirus allows information to ‘crossover’ between modules to enhance detection
capabilities. It’s like a wrapper that allows all the parts inside
to talk to each other and work in a cohesive manner.

Antivirus MONitor (AMON) : An on-access (memory-resident)
scanner, which automatically scans files before they're accessed.
NOD32
: An on-demand scanner, which can be run manually
on specific files or disk segments. It can also be scheduled to run during
off-peak times.
Internet MONitor (IMON) : A memory-resident
scanner that runs on the Winsock level to prevent infected files from reaching
the computer's disks. Its scans internet web browsing traffic (HTTP) and
incoming e-mail via the POP3 protocol.
E-mail MONitor (EMON) :
An auxiliary module for scanning incoming/outgoing e-mails via the MAPI
interface, such as Microsoft Outlook Microsoft Exchange.
Document
MONitor (DMON) : Utilizes the proprietary
Microsoft API for scanning Microsoft Office documents (including Internet
Explorer).
