McAfee VIRUSSCAN 4.5 Administrator's Manual page 59

The following sections describe some common scenarios that use command-
line options to run custom installations.
Silent installation
Use command-line options to set up VirusScan software on each network node
with little or no interaction from end users. During a silent installation, Setup
does not display any of its usual wizard panels or windows, or offer the end
user any configuration options. Instead, you pre-configure these choices and
run Setup in the background on each target workstation. If you want, you can
install VirusScan software on any unattended workstation with or without the
end user's knowledge, provided you have all the necessary administrative
privileges.
setup/q/i
Use /q to run a silent installation. The /i should always appear last on the
command line. It tells Setup to locate the .MSI file that controls the installation.
– PRESERVESETTINGS. This property tells Setup whether it should
retain the configuration options you used for previous VShield
scanner installations. By default, its value is True.
– REBOOT. This property tells Setup whether it should restart your
computer. You can either force the computer to restart, or prevent it
from restarting.
– REMOVE. This property tells Setup to remove one or more program
components. You can specify a particular component, or use the
value ALL to remove all components. If you combine this property
with the ADDLOCAL property, you can install all but one or two
specific components.
– REMOVEINCOMPATIBLESOFTWARE. This property tells Setup
to remove previous VirusScan versions or other anti-virus software
that could conflict with this VirusScan version. By default, its value
is True.
– STARTONACCESSSCANNER. This property tells Setup to start the
VShield scanner after it finishes the installation. By default, its value
is True.
– USEADMINONLYSECURITY. This property tells Setup which
security mode you want this VirusScan copy to use when it runs.
Possible values are 0, which runs the software with standard
security, and 1, which runs the software with maximum security.
