Filezilla used to excellent. However, I used the download link on the site and the source forge download it links to has now become contaimenated with Malware. I had to clear the Lasaoren malware off my computer due to it.
A real shame that this has become tainted as it was an excellent FTP software.
FileZilla, especially the recommended SourceForge installer, must now be considered malware.
It installs unwanted adware; even after rejecting a software offer in the download dialog, another adware installed with Filezilla, which popped up about a minute after starting the FTP client.
I read before that questionable software is offered by the installer, but in my case, the installed adware had no install dialog, not even one with a pre-set checkbox.
The main developer is, as seen in the forum, fully aware of the issues and supports these practices, keeps claiming falsely that no unwanted things would be installed (the old "your own fault when not reading fine print" scheme), for gaining revenue this way.
Stay away from this kind of software and it's distributors! This kind of malware, adware, spyware, browser hijackers, is a still growing pest, with once reputable companies, like Oracle or SourceForge spreading it.
