Using the VShield Scanner
To modify the settings in this property page, follow these steps:
1. Select the Enable Internet download scanning checkbox.
The options in the rest of the property page activate.
2. Specify the types of files you want the Download Scan module to
examine. You can:
• 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 Download Scan
module will examine, click
Extensions to open the Program File
Extensions dialog box ( Figure 4-10 ).
Figure 4-26. Program File Extensions dialog box
• Scan all files. Select the All files button to have the Download Scan
module examine any file, whatever its extension, whenever you or
a system process modifies it in any way.
• Scan compressed files. Select the Compressed files checkbox to
have the module look for viruses in compressed files or in file
archives.
