You can:
• Scan compressed files. Select the Compressed files checkbox to
have the VirusScan application look for viruses in compressed files
and file archives. Although it does give you better protection,
scanning compressed files can lengthen a scan operation.
To see a list of the types of files and archives that the application
scans, see "Current list of compressed files scanned" on page
• Scan all files. Select the All Files checkbox to have the application
scan all of the files on the target you specified, whatever their
extensions.
Š
NOTE: McAfee recommends that you choose this option for
your first scan operation, or periodically thereafter, to ensure
that your system is virus-free. You can then limit the scope of
later scan operations.
• Choose file types. 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 operations to those
files most susceptible to virus infection. To do so, click the Program
files only button.
To see or designate the file name extensions the application will
examine, click Extensions. This opens the Program File Extensions
dialog box. To learn about how to change the files listed there, see
"Adding file name extensions for scanning" on page
