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.
This is why I refuse to use any download buttons on websites for FOSS apps; if it’s FOSS, it has a link to the source, which has releases, and is the safest way to ensure you’re getting what you actually want.
Forked, malware added?
No, I tried it in a VM and it’s a completely different app. It seems like a shitty electron app that sits forever in the tray wasting ram just to upload files in their cloud for conversion instead of converting locally. And then it shows prompt to subscribe from the tray
