Using Specialized Scanning Tools
Choosing Detection options
When you first open the E-Mail Scan Properties dialog box to configure a scan
operation, the E-Mail Scan extension assumes that you want it to scan all of the
messages in your Inbox, to scan all message file attachments, to scan
compressed files, and to scan only those files susceptible to virus infection.
The E-Mail Scan extension does in fact scan the e-mail messages themselves,
as Microsoft Exchange files can carry embedded macros, Hyper Text Markup
Language (HTML) tags, and VBScript applets, all of which can in turn harbor
specialized viruses, worms, or Trojan horse programs.
Š
NOTE:
The E-Mail Scan extension connects directly to your mailbox
on your Microsoft Exchange mail server to run its scan operations.
You can also scan any public folders to which you have access, but
the extension does not scan messages stored in Microsoft Outlook
personal folders (.PST files) or archived items. Other VirusScan
components, however, will scan .PST files during their own regular
scan operations unless you specifically exclude them.
To change these settings, follow these steps:
1. Choose which e-mail messages you want the E-Mail Scan extension to
examine for viruses. You can scan:
• All messages in the ‘Inbox’ folder . Click this button to have the
extension look for viruses in all e-mail messages stored in your
Microsoft Exchange or Microsoft Outlook Inbox, whether you have
read them or not.
If you have a large volume of messages stored in your Inbox, such a
scan operation can take considerable time. If, however, you installed
the E-Mail Scan extension after you have installed and used your
mail system for some time, McAfee VirusScan Software
recommends that you perform at least one such scan operation to
ensure that your older mail messages do not contain viruses.
Š
NOTE: Once you download mail to your computer, VirusScan
software treats your personal folder or archive file as it would
any other file, unless you specifically exclude it from scan
operations. This gives you an added layer of anti-virus
security.
• All highlighted messages . Click this button to have the extension
look for viruses in only those e-mail messages you select from those
stored in your Microsoft Exchange or Microsoft Outlook Inbox.
