Is this really working? .vbs--i know a virus named astig.vbs--this infected lots of pc in my friends intrnet sh0p and its really hard to remove.is this a virus?will i be able to delete it?
.vbs is just an executable Visual Basic Script, you should only really run them if you know exactly what it's doing.
The good thing about .vbs and .bat (another popular executable file which is sometimes used as a quick virus attempt by script kiddies) is that all of the code is visible by simply just opening the file in a text editor.
The code in saishashank96's post is harmless: it's creating two blank variables (msg and sapi), prompting the user for some text in the form of a text box and saving the input into the msg variable, assigning the Microsoft voice object into the sapi variable, then just passing the message into the speak function of the sapi object (which makes it speak).
