5. Specify the types of files you want the ScreenScan utility to examine. You
can
• Scan compressed files. Select the Compressed files checkbox to
have the utility look for viruses in compressed files or file archives.
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 subfolders within the designated target. Select the Include
subfolders checkbox to have the utility look for viruses in any
folders inside your scan target.
NOTE: Choosing Include subfolders causes the utility to scan
only those files stored in the subfolders themselves. The utility
will not scan files stored at the root level of the folder you
designate. To scan those files, clear the Include subfolders
checkbox.
• Scan all files. Select the All Files checkbox to have the utility scan
all of the files in the mailbox or public folder you specified,
whatever their extensions.
NOTE: Dr Solomon's 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 ScreenScan utility
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
6. Turn on heuristic scanning. Click Advanced to open the Advanced Scan
Settings dialog box (see
Heuristic scanning technology enables the ScreenScan utility to
recognize new viruses based on their resemblance to similar viruses that
the module already knows. To do this, the utility looks for certain
"virus-like" characteristics in the files you've asked it to scan.
