No, it is very accurate. Just try downloading it from Sourceforge. Chrome will block your download.
You can also try installing it. Your Windows installation will be crawling with malware before you know it.
We're talking about the official download here. No third-party sites.
The last time I tried FileZilla server, it infected my computer. FileZilla client is the same (on Windows). I've once documented the use of FTP for customers and advised using FileZilla. Once they started to get malware infections, I needed to retract that document fast.
You were right to go looking on the FileZilla forums. Take a look at the
'General' section and count the number of topics about malware in the official installer. It really is a shame.
