Your copy of the System Scan module will then examine files
as your computer reads them from your hard disk, then again
asit writes themto thedestination computer’sharddisk. If the
destination computer has its own copy of the System Scan
moduleactive,ittoowillscanthefileasyouwriteittothe
network drive if that System Scan module has the Inbound
files checkbox selected.
Ifyoutendtocopyfilesfromoneserverthatdoesnotcopy files
from your computer, and if other network users do the same,
you might want to configure your computers to scan only files
thattheywrite to theirhard disks—oronly files that they read
fromtheirharddisks—inordertopreventtwocomputersfrom
scanning the same file. If you do so, however, you should
configureeach computer identically.Otherwise,onecomputer
that scans only outbound files could copy an infected file from
a server that scans only inbound files.
• Scan files on floppy disks. Boot-sector viruses can hide in the boot
blocks ofany formatted floppydisk, thenload into memory assoon
as your computer reads your floppy drive. Select the Access
checkbox to have the System Scan module examine floppy disks
each time your computer reads from them or writes to them. Select
the Shutdown checkbox to have the module scan any floppy disks
that you leave in your drive as you shut down your computer. This
ensures that no viruses can load when your computer reads your
floppy drive at startup.
3. Specify the types of files you want the System Scan module to examine.
You can
• Scan compressed files. Select the Compressed files checkbox to
have the module look for viruses in compressed files or in file
archives. This option ensures that viruses do not spread from
compressed files, but because the module uncompresses these files
before it scans them, choosing this option can lengthen the time it
takes to scan a given set of files as you work with your computer.
 NOTE: When the SystemScan module examines a file archive,
it will scan only the file archive itself, not the compressed files
within the archive. To learn which files and archives the
module scans, see “Current list of compressed files scanned”
on page 318.
