It appears that Unchecky cannot detect "Browser Security" popping up when somebody tries to install "DVDStyler" and "Browser Security by Vondos Media GmbH" goes undetected.
We could not reproduce the offer. Can you provide more details, such as a screenshot and an exact link? Thanks.
You need to download EU installer http://www.dvdstyler.org/download/DVDStyler-3.0.3-win32-bs.exe
