How to disable auto save on Emacs 26.1

[Tom Wallenfang <tom@wallenfang.de>]

Hello dear emacs folk,
I have been seeing lately that the autosave feature is activated again
although I deactivated it :/

Here is a cut from my .emacs file:

> (custom-set-variables
> '(auto-save-default nil)
> '(auto-save-interval 0)
> '(auto-save-timeout 0)
> '(auto-save-visited-interval 0))
Does anyone here know what I have to do so I don't have to remove those
files everytime I quit editing

(yes, I do know the consequences that can come with disabling autosave,
and I am taking the full responsibility for what might/is going to
happen.)

Thanks in Regards
Tom
