Open-Source Availability
FileZilla Client source code is publicly available under the GNU General Public License version 2.0. Independent developers and security researchers can review, compile, and audit the codebase. This transparency is a cornerstone of FileZilla's trust model and distinguishes it from closed-source commercial FTP clients.
Antivirus False-Positive Clarification
Why Antivirus May Flag FileZilla
Some antivirus engines classify FileZilla as a potentially unwanted program (PUP) rather than malware. This typically occurs because older installer bundles included optional third-party software offers, or because FTP clients are occasionally misused by bad actors. The FileZilla application itself does not contain spyware, adware, or trojans.
