Question/Issue:
You want to know which options or switches can be used with the Symantec AntiVirus DOS scanner (Navdx.exe).


Solution:
Navdx.exe usage and options:

NAVDX [pathname] [options]

pathname	Any valid drive, directory, file, or combination of items.
/?	Displays the help screen.
/A or /L	Scan all drives or local drives. Drives A and B are skipped.
/B[+|-]	Enable or disable scanning of boot records.
/BOOT	Only scan the boot sectors of specified drives.
/M[+|-]	Enable or disable scanning of memory.
/MEM	Only scan memory.
/HEUR[0|1|2|3]	Set Bloodhound sensitivity. (0 disables)
/S[+|-]	Enable or disable scanning subfolders.
/REPAIR	Repair infected files automatically.
/DELETE	Delete infected files automatically.
/PROMPT	Prompt for repair or delete on each infected file.
/HALT	Halt the system when a virus is found.
/CFG:[directory]	Specifies the directory that contains Norton AntiVirus configuration files.
/LOG:file	Create a log file.
/APPENDLOG:file	Append to a log file.
/DOALLFILES	Scan all files, not just executables.
/ZIPS	Scan files in compressed files.
/NOBEEP	Do not generate sounds.
/HELPERROR	List all possible DOS error levels that NAVDX returns.

• The /REPAIR and /DELETE switches cannot be used together. You must use one or the other; if used together, only the first switch will be run.
• If you use the /REPAIR switch and Navdx cannot repair an infected file, it will do nothing. It is strongly recommended, therefore, that you first run the scan using the /REPAIR switch. If the summary report generated by Navdx shows that there were files that it was unable to repair, run the scan a second using the /DELETE switch.
  
  An alternative to this is to run one scan and use the /PROMPT switch. This will prompt for an action (repair or delete) for each file that is detected as infected. If there are many infected files, however, this could be very time consuming, as it requires a response for each one.

• When you run Navdx from a floppy disk, Navdx will automatically try to find and use the definitions on the hard drive. If the current definitions are on floppy disks, then use the /cfg: switch to direct it to use the definitions on the floppy disk. For example, if the floppy disk drive is drive A, type the following:
  
  navdx /cfg:a
  
• If you use the /cfg:a switch with other switches, then it should appear before the other switches, as in the following example:
  
  navdx /cfg:a /a /doallfiles /repair
  
• Navdx does not have a quarantine option.
