You know what? I didn't believe you, since I'm using it for a long time on Linux and never had any issues with it. Today, when I helped a friend (on Windows) with some SFTP transfer and recommended FileZilla was the first time I realised the official Downloads page provides Adware. The executable even gets flagged by Microsoft Defender and VirusTotal. That's actually REALLY bad. Isn't FileZilla operated by Mozilla? Should I stop using it, even though the Linux versions don't have sketchy stuff? It definitely leaves a really bad taste.
