URL decode

Ciao a tutti!

It is possible to decode this URL "Z=W=NQobdvHNRmwLOzit82vYZ1TJN2iaMuTlcGxbYuWI" using vb6?

This address is in http://adf.ly/RiDRb HTML page.

Last week look like this: var zzz = ' http://adf.ly/RiDRb ' and now look like:

var zzz = 'Z=W=NQobdvHNRmwLOzit82vYZ1TJN2iaMuTlcGxbYuWI'


So, how to decode this URL?

Thanks for any help!
