Using the VShield Scanner
36 McAfee VirusScan
When the VShield scanner first starts, it displays an icon in the Windows
system tray that indicates which of its modules are active. To learn what each
icon state means, see “Understanding the VShield system tray icon states” on
page 39.
At first, the scanner enables only its System Scan module, which scans viruses
that arrive on your system from floppy disks and other removable media,
from local-area network connections, and similar areas. The System Scan
module also scans files that arrive via your e-mail system and from the
Internet, but to do so, it requires the aid of the other VShield modules: E-Mail
Scan, Download Scan, and Internet Filter.
Ë IMPORTANT: To use the E-Mail Scan, Download Scan or Internet Filter
modules, you must install them from the Custom option in Setup. To
learn how to do so, see Chapter 2, “Installing VirusScan Software.”
If your computer runs Windows NT Workstation v4.0 or Windows 2000
Professional, the VShield scanner loads as a Windows NT service called
VShield, which you can see in the Windows Services control panel.

NOTE: McAfee recommends that you do not start or stop the VShield
service from the Windows control panel. Instead, you can stop and
restart the scanner from the provided VirusScan control panel. To learn
more about how to use the VirusScan control panel, see “Understanding
the VirusScan control panel” section of the VirusScan User’s Guide.
If your computer runs Windows 95 or Windows 98, the scanner loads in a way
that mimics a Windows service on that platform. This service is not visible in
the Windows user interface.
Starting the scanner automatically
If the VShield scanner does not start automatically, you can set it to do so in
the VirusScan control panel.
Follow these steps:
1. Click Start in the Windows taskbar, point to Settings, then choose
Control Panel.
2. Locate and double-click the VirusScan control panel to open it.
3. Click the Components tab (Figure 5-1).
