VBScript (short for Visual Basic Script Edition)
Is an interpreted language for the Microsoft Windows Scripting Host.
Its syntax reflects its origins as a variation of Visual Basic programming language. It has made significant support from Windows administrators as automation tool because, joint and parallel improvements in Windows operating systems where it operates essentially allows more leeway and flexibility than the batch language (or batch) developed in the late 1970s for MS-DOS.
VBScript is the language used to write some famous network worms, such as I Love You. This is due to several reasons. First, resembling a blue parchment representing the .vbs file icon may lead to inexperienced users think that this is a text file. Second, it is easy to write a VBScript worm that spreads via e-mail (few lines of code required). Microsoft has fixed security holes exploited by these malicious programs. This does not mean eradicated solved, it has only complicated the process; because if for example the I Love You spread via Outlook, now if you use the same method comes a warning, so that is commonly employed methods such as sending by SMTP server (rather more complex to program than by other method).
