Uninstall McAffee or Avast (or any other) antivirus

Thank you for helping! And it was AVG I think was my Antivirus.. BUT IT WORKED!
Internet hug
I reeeaally like giving anyone hugs C:

Keep in mind, that this only a workaround. An antivirus software is not only using space on your harddisk, it has of course a purpose.
i have the same issue, hope it gets fixed
