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.
