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.
Makes sense.
Its literally a weekend job and a few bucks to quickly set up a fake site. Even with a single $20 donation are you already recouping your losses.
