Actually simply deleting something on a PC does not really remove it, it just marks the space to be over-written as needed, all the code is still there, the only real way to remove/over-write data is to use one of the options in this guide at the link below.
That is why I stipulated for practical purpose its gone. It is still there in the $Recycle Bin to be wrote over if I remember correctly. You can empty the $Recycle Bin or Clean the free space and get rid of it. I do that after cleaning out a virus. It would take forever on todays very large drives.
