Most security alerts about FileZilla are false positives. Antivirus programs often tag FileZilla as a Potentially Unwanted Application (PUA) because of offers bundled into the installer. Here are the answers to the questions people ask most.
Is FileZilla safe to download?
Yes, when you download it from the official FileZilla website. Every installer we distribute is checked by 2Checkout before release.
Why does my antivirus flag FileZilla?
Antivirus tools often tag FileZilla as a Potentially Unwanted Application (PUA) because the installer can include optional offers from sponsors. You can decline them during setup. If you find a false positive, report it to your antivirus vendor. There is no virus in the offer-enabled installer.
How do I install FileZilla without bundled offers?
Download the installer from the official website, then read each screen of the setup and decline any optional offers or extra software before you continue.
Official download: FileZilla Client — Official Download. For step-by-step instructions, see how to install FileZilla.
How do I check that the installer is genuine?
Right-click the installer, open Properties, and go to the Digital Signatures tab. Confirm the signature is issued to FileZilla Project with no warnings, and install only if it checks out.
