• Scan files on floppy disks. Boot-sector viruses can hide in the boot
blocks of any formatted floppy disk, then load into memory as soon
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.
Š
NOTE: When the System Scan 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
on page
• Choose file types for scanning. Viruses cannot infect files that
contain no executable code, whether script, macro, or binary code.
You can, therefore, safely narrow the scope of your scan 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
