• Scan compressed files. Select the Compressed files checkbox to
have the E-Mail Scan extension look for viruses in compressed files
and file archives. Although it does give you better protection,
scanning compressed files can lengthen a scan operation.
The extension scans the same types of compressed files and archives
that the VirusScan application does. To see a list of those files and
archives, see "Current list of compressed files scanned" on page
• Scan all files. Select the All Files checkbox to have the E-Mail Scan
extension scan all file types in your mailbox, whatever their file

NOTE: McAfee recommends that you choose this option for
your first scan operation, or periodically thereafter, to ensure
that your mailbox 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 types that the E-Mail Scan extension will
examine, click Extensions. This opens the Program File Extensions
dialog box. To learn about how to change the files listed there, see
