There's no native API* for File System access in browsers. You need that first!

For example, in Internet Explorer, there's an ActiveX object for it:

var fso = new ActiveXObject("Scripting.FileSystemObject");

...but it requires the user to relax their browser settings. On other browsers, you may be able to use a jar (Java Archive) file.

You could also see what non-browser JavaScript containers offer, e.g. Microsoft HTA files (HTML Application) will support the Windows ActiveX FileSystemObject fine, providing your Virus Checking Software allows HTA files to execute.
