OVERVIEW
Scripts are generally written code that are interpreted and implemented by another application. In contrast, compiled programs can run on their own, but are often harder to produce as they have to be compiled.
Malware authors have taken advantage of relative ease of producing scripts and have produced significant numbers of script malware - many of which are written using Visual Basic Script, JavaScript, and HTML.
Many scripts can run on most systems without the installation of a special interpreter program. For example, certain Windows systems have Windows Scripting Host, which can interpret different script types. Also, HTML scripts are loaded by Web browsers, which are commonly installed on most computers.
This malware may be dropped by other malware.
