Using the VShield Scanner
100 McAfee VirusScan Anti-Virus Software
"Inbound" files are files that your computer or another system on
the network saves or writes to local hard disks attached to your
computer or to any network hard disks you have mapped to your
system. To include network drives mapped to your system for a
scan session, you must also select the Network drives checkbox.
Your system can receive data from your computer's memory, from
a floppy disk in your computer's floppy drive, from other systems,
from e-mail, or from other sources, then write that data to a file on
your hard disk. The VShield scanner treats all such data as
"inbound."
"Outbound" files, meanwhile, are files that your computer or other
systems on the network read from local hard disks attached to your
system or from network disks mapped to your system. To include
network drives mapped to your system for a scan session, here too
you must select the Network drives checkbox.
Whenever your computer or another system reads data from a file
stored on a local hard disk attached to your system or a network
disk mapped to your system, the System Scan module treats that
data as "outbound."
Š
NOTE: If you have network drives mapped to your computer
from which you copy files, or if other network users copy files
from your computer, McAfee strongly recommends that you
have the VShield scanner installed both on your computer and
on the computer that "owns" the network drive. You should
also select all checkboxes in the Scan area in the Detection page,
plus the Network drives checkbox in the What to Scan area.
Your copy of the System Scan module will then examine files
as your computer reads them from your hard disk, then again
as it writes them to the destination computer's hard disk. If the
destination computer has its own copy of the System Scan
module active, it too will scan the file as you write it to the
network drive if that System Scan module has the Inbound
files checkbox selected.
If you tend to copy files from one server that does not copy files
from your computer, and if other network users do the same,
you might want to configure your computers to scan only files
that they write to their hard disks—or only files that they read
from their hard disks—in order to prevent two computers from
scanning the same file. If you do so, however, you should
configure each computer identically. Otherwise, one computer
that scans only outbound files could copy an infected file from
a server that scans only inbound files.
