Where to get this Viral script?

I have come across a lot of different sites that use the same viral script. Here is an example of it from a random website: mspxblfree.com/xbox/ Where could I get this from?

Go to scriptzmafia or any other nulled stuff providing sites. Search with 'viral' keyword and you'll get this type of app somewhere. If you are interested in serious and advanced viral apps then simply PM me.
