2. Specify the types of files you want the VirusScan application to examine.
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.
• 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 VirusScan Software 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.
3. Turn on heuristic scanning. Click Advanced to open the Advanced Scan
Settings dialog box
