Access MONitor (AMON) Configuration

AMON (Access MONitor) is a memory-resident (always running when
computer is on) file scanning program. Automatic starting of AMON after
computer restart is a fundamental defense against malicious code. Quitting
AMON is not recommended and should only be done under special
circumstances. Execution of two different antivirus monitors (from different
products or companies) is not recommended since it may make your computer
slower and/or cause a system crash, especially on Windows NT systems,
might lead to serious problems.
AMON is the most important line of antivirus defense. It is critically important to
keep it running at all times using the most current version of the virus signature
databases and NOD32 program upgrades. AMON monitors all potentially
threatening actions on protected computers such as opening, executing,
creating or renaming files.
