Files with the .VBS extension contain scripts written in Microsoft’s Visual Basic Scripts Edition, a language derived from the Visual Basic language for use by Microsoft – namely in the Internet Explorer browser and the Windows system. The file can also use a .VB extension.

The VBS script code can be executed in IE or in the system shell using an application, namely a script host based on Windows called Wscript.exe. Scripts from unknown sources should be approached with caution, as they can contain malware – also known as viruses.
