Macro
viruses/malware are application-specific. They infect macro utilities
that accompany such applications as Microsoft Word (
.doc)
and Microsoft Excel (
.xls). Therefore, they
can be detected in files with extensions common to macro capable
applications such as
.doc,
.xls,
and
.ppt. Macro viruses/malware travel between
data files in the application and can eventually infect hundreds
of files if undeterred.
As these file types are often attached to email messages, macro
viruses/malware spread readily by means of the Internet in email
attachments.
ScanMail prevents
macro viruses/malware from infecting your Exchange server in the
following ways:
-
Detects malicious macro code using heuristic scanning.
Heuristic
scanning is an evaluative method of detecting viruses/malware. This
method excels at detecting undiscovered viruses/malware and threats
that do not have a known virus signature.
-
Strips all macro code from scanned files.
