Footnote without reference

Question

I am currently writing my bachelor thesis with LaTeX and I want a footnote without a reference. I used a blank footnote with:
    begingroup
    renewcommandthefootnote{}footnote{#1}%
    addtocounter{footnote}{-1}%
    endgroup}

It makes me a footnote  at the end of a page without a number as I wish, but then a red box appears at the end of the page in the pdf. With footnotetext, I can create a footnote without the reference, but it needs a number. Is there an option to get rid off the reference AND the number?
Currently its like this: (I need the hyperref-package for url and references and the other footnotes)
documentclass[a4paper, 12pt, bibtotocnumbered]{scrartcl}
usepackage{hyperref}
newcommandblfootnote[1]{%
    begingroup
    renewcommandthefootnote{}footnote{#1}%
    addtocounter{footnote}{-1}%
    endgroup
}
begin{document}
I want a footnote without reference and without a number.blfootnote{This creates a footnote without number but with reference.}
end{document}

Adding the hidelinks option to hyperref in your preamble should do the trick (see here). Put into a MWE:
documentclass[a4paper, 12pt, bibtotocnumbered]{scrartcl}
usepackage[
hidelinks % hide link outlines
]{hyperref}
newcommandblfootnote[1]{%
    begingroup
    renewcommandthefootnote{}footnote{#1}%
    addtocounter{footnote}{-1}%
    endgroup
}
begin{document}
I want a footnote without reference and without a number.blfootnote{This creates a footnote without number but with reference.}
end{document}

Here, freefootnote will create the desired footnote without a number and without a link.  As shown in the MWE, it does not interfere with the use of linked, numbered footnotes elsewhere in the document.
documentclass[a4paper, 12pt, bibtotocnumbered]{scrartcl}
usepackage{hyperref}
letsvthefootnotethefootnote
newcommandfreefootnote[1]{%
  letthefootnoterelax%
  footnotetext{#1}%
  letthefootnotesvthefootnote%
}
begin{document}

freefootnote{This creates a footnote without number 
  and no longer with reference.}
