In any case, if your PC stored any copy of such a file, would be enough for deleting it, to clean free space with zeros?
Who knows?
As said it may depend on a number of factors IF the file is actually copied, IF it is actually "normally" deleted after having been run, etc., etc.
If you find the area occupied by that file on disk (if any) and fill that area with 00's (and that area may or may not be "free space") yes, the file is "gone forever".
