One of those two sites is distributing adware. Which of them?
File Converter (FOSS) by Adrien Allard was hosted on file-converter[.]org since a decade. Then someone a few weeks ago snatched that domain and it’s now distributing adware. Almost identical design for the page, 100% designed to deceive users to download a different product, as it’s called Zamzar.
.io vs .org? Different website, old, legitimate domain still intact yes?
legitimate domain changed from .org to .io on 1st feb according to this commit https://github.com/Tichau/FileConverter/commit/0645481801ccb8f46a8e0766e9edac9acf77f468
