• Choose file types for scanning. Virusescannotinfectfilesthat
contain no executable code, whether script, macro, or binary code.
You can, therefore, safely narrow thescope of yourscan sessions so
that the module examines only those files most susceptible to virus
infection.To do so, select the Program files only button.
To see or designate the file name extensions that the System Scan
module will examine, click Extensions to open the Program File
Extensions dialog box (Figure 4-10).

See “Adding file name extensions for scanning” on page 313 and
“Current list of vulnerable file name extensions” on page 314 to
learn which file name extensions this module scans by default and
how to add to or change this list.
• Scan all files. Select the All files button to have the System Scan
module examine any file, whatever its extension, whenever you or
a system process modifies it in any way.
• Scan networked drives. To have the System Scan module look for
viruses on any drives mapped to your system that you use in any
way, select the Network drives checkbox.
 NOTE: If you have network disks mounted on your system,
the System Scan module treats any files your system writes to
such drivesas “inbound” files and any files your system reads
from such drives as “outbound” files. To ensure complete
