There is a malware version of Filezilla but the link I provided should be OK as long as you download the application from that site.

I just downloaded and Malwarebytes blocked the installation. Malware flagged a file fusion.dll and recommended deleting that file. I did and the install went fine after that.

I have been using CuteFTP for years but I rarely need it. You can download a free trial version here https://www.globalscape.com/cuteftp
