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 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
