Scanning Microsoft Exchange and Outlook mail
Dr Solomon's Anti-Virus provides you with two complementary methods to
protect your Microsoft Exchange or Outlook e-mail system:
• The VShield scanner includes an E-Mail Scan module that runs continuous
background scan operations on e-mail as it arrives on your server.
• The E-Mail Scan extension allows you to scan your mailbox on the
Exchange server at your own initiative, and at times convenient for you.
An unobtrusive plug-in architecture gives you access to the E-Mail Scan
extension from directly within your Exchange or Outlook client application.
When and why you should use the E-Mail Scan extension
Most of the fastest-spreading viruses, worms, and other hostile agents that
have emerged in the last few years have proliferated via e-mail. E-mail offers
a fast and omnipresent medium that virus writers can use to distribute
infected attachments, which they often trick users into opening and activating.
Newer viruses, as VBS/BUBBLEBOY demonstrated, might even be able to
work without users having to open or read even the e-mail message itself.
The Microsoft Exchange and Outlook e-mail clients are particularly vulnerable
to infections of this sort because of their powerful macro and script
interpretation capabilities. As with the rest of the Microsoft Office application
suite, the Exchange client software makes extensive use of macros, marked-up
text, script commands, and similar capabilities that lend themselves to virus
attack.
Use the VShield E-Mail Scan module to run background scan operations on
your e-mail system and to maintain a constant level of vigilance between the
scan operations you run with the E-Mail Scan extension. Under most
circumstances, this should protect your system's integrity.
If you have a large backlog of mail on your server that you have not yet
scanned, if you log off from your Exchange server, or if you stop the E-Mail
Scan module at any point, you should use the E-Mail Scan extension to scan
your mailbox to ensure system integrity. Viruses could easily remain in old
e-mail messages stored on your server or in e-mail messages that arrive during
periods you are logged off from your e-mail system.
