This file could be anything; however, usually a file with extension VBS is a
VBScript file. It is a text file and can be viewed using NOTEPAD. Unlike
other text files, a VBS files can be executed by
1. double clicking on it
2. supplying the file name to WSCRIPT.EXE as an argument (Start | Run)
3. supplying the file name to CSCRIPT.EXE as as argument from the Command
Prompt.

Opening the file using a text editor does NOT execute its code; so if you
can recover it, examine it using NOTEPAD.
