Installing VirusScan Software
Scanning your system at startup
By default, Setup adds a line to the AUTOEXEC.BAT file for Windows 95 and
Windows 98 systems that tells the VirusScan application to scan the master
boot record (MBR) when your computer starts. To prevent Setup from doing
so—during a silent installation, for example—add the property
SCANATSTARTUP to the command line with the value False:
setup SCANATSTARTUP=False
Starting the VShield scanner
By default, Setup starts the VShield System Scan module if the installation
does not require you to restart your computer—if you remove earlier
VirusScan versions during installation, for example. To keep Setup from
starting the VShield scanner, add the STARTONACCESSSCANNER property
to the command line with the value False:
setup STARTONACCESSSCANNER=False
Preserving on access settings
By default, Setup preserves your VShield settings from previous VirusScan
installations. To install the new VirusScan version without previous settings,
add the PRESERVESETTINGS property to the command line with the value
False:
setup PRESERVESETTINGS = False
Running Setup from a login script
To install VirusScan software at the time each of your target computers starts,
you can add a Setup command line to your login script and include any logic
you think necessary to ensure that the installation will run once—checking for
the VirusScan default program directory, for example. The command line
should include all of the options and properties you want to use to govern how
Setup runs.
If you run the login script from a Windows 95 or Windows 98 workstation,
you must add the option /LSCRIPT to the command line if the target computer
has any previous VirusScan version installed, or if it might not have Microsoft
Installer (MSI) v1.1 installed. Unlike other options, the /LSCRIPT option is
case sensitive and must appear in the command line with all capitals.
Without the /LSCRIPT option, Setup will run and, if you do not have MSI v1.1
installed or if you have a previous VirusScan version on the target computer,
will require the target computer to restart. Before it does so, however, it places
a flag in the Windows RunOnce registry key.
