CHAPTER 4 107
Using F-Secure Anti-Virus for Microsoft Exchange
Scan all attachments except with these
extensions
- Scan all attachments except those
with specified filename extensions.
You can add new file types on the extensions
lists by typing the file extensions in the file
extensions text boxes. Separate the extensions
by spaces.
Scan mail message
bod
y
Specify whether the body of the e-mail message
should be scanned for malicious code.
By default, F-Secure Anti-Virus for Microsoft
Exchange scans message bodies.
Although scanning message bodies can slow
down the performance, it is recommended as a
virus can be carried inside a message body.
Enable File Type
Recognition Trojans and other malicious code can disguise
themselves with filename extensions which are
usually considered safe to use. Intelligent File
Type Recognition can recognize the real file type
of the message attachment and use that while
the attachment is processed. Specify whether
you want to use Intelligent File Type Recognition
or not.
By default, Intelligent File Type Recognition is
disabled during the real-time processing.
Intelligent File Type Recognition strengthens the
security - you can block unsafe content that has
a safe filename extension (for example, a
Microsoft Word document using the ‘rtf’ filename
extension) and you do not accidentally block
safe content that has unsafe filename extension
(for example, a text file using the ‘doc’ filename
extension). Intelligent File Type Recognition can
degrade the system performance.
