Using VirusScan Command-line Options
/NODDA On-demand
scanning only
No direct disk access. This prevents the scanner
from examining the boot record.
This feature has been added to allow the scanner
to run under Windows NT.
You might need to use this option on some
device-driven drives.
Using /NODDA with the /ADN or /ADL switches
may generate errors when accessing empty
CD-ROM drives or empty Zip drives. If this occurs,
type F (for Fail) in response to the error messages
to continue the scan.
/NODISK On-access
scanning only
Does not scan boot sector while loading the
VShield scanner.
/NODOC On-demand
scanning only
Does not scan Microsoft Office files.

memory (XMS).
/NOEXPIRE On-demand
scanning only
Disables the “expiration date” message if the
VirusScan data files are out of date.
/NOMEM None Does not scan memory for viruses.
This greatly reduces scan time.
Use /NOMEM only when you are absolutely
certain that your computer is virus-free.
/NOREMOVE On-access
scanning only
Prevents users from removing the VShield scanner
from memory with the /REMOVE switch.
/NOWARMBOOT On-access

disk in drive A: for viruses during warm boot
(system reset or
CTRL+ALT+DEL).
/NOXMS On-access

drive(s).
