224 McAfee VirusScan
Good anti-virus security measures incorporate complete, regular scan
operations on your mailbox because:
• Good security is redundant security. The VShield E-Mail Scan module
looks for virus code as your e-mail arrives on your server, or as executable
attachments run after they’ve downloaded to your system. The E-Mail
Scan extension, however, can scan old e-mail stored on the server that the
E-Mail Scan module will not see, look for viruses in e-mail that arrives in
between times you log in to your Exchange server, or can scan your
mailbox if you’ve temporarily disabled the VShield E-Mail Scan module.
• Preventative maintenance means safety. With fast e-mail connections
between powerful, web-enabled, scripted client software, it takes only a
moment to get infected, sometimes even before you open your mail.
Regular scan operations can often catch infections before they spread or do
any harm.
Using the E-Mail Scan extension
To use the E-Mail Scan Extension, you must install VirusScan software with a
Custom installation and choose the E-Mail Scan component for installation
(see
“Installation steps” on page 32 for details). To use the E-Mail Scan
extension with its default settings, first start your Microsoft Exchange or
Microsoft Outlook client software.
Next, follow these steps:
1. Log on to your mail server as you would normally.
2. Choose Scan for Viruses from the Tools menu, or click in the
Exchange or Outlook toolbar.
Š
NOTE: If you use Microsoft Exchange 5.0, a limitation in the way
the program updates its toolbar prevents the E-Mail Scan extension
buttons from appearing immediately. To add the Scan for Viruses
button to the toolbar, choose
Customize Toolbar from the Tools
menu, then add the E-mail Scan extension buttons from the list of
available buttons in the Customize Toolbar dialog box.
Once you’ve started it, the E-Mail Scan extension will immediately begin
to scan your Exchange or Outlook mailbox for viruses (see
Figure 7-1 on
page 225 ).
