strongly recommend you to remove those information and purge the server immediately. It's just matter of time before someone take over the server, change the password, turn your server into botnet and your server provider decide to purge the server (and possibly ban/freeze your account).
@LoyceV and @TryNinja please redact those information from your website.
Too late aAt this point google and a few others probably already have archives of it. @Alexeymalutin change the password and check your access logs.
That or just wipe the server and start again.
Back to the original issue, IF you are 100% sure it's not some AV grabbing the file and removing it since it never makes it out of the temp folder I would look at the server closing the connection before it's finished and the desktop just removing what it thinks is an incomplete file.
Also could your front end router for the PC be doing any kind of filtering? More and more home routers are coming with some for of AV so it could be killing the download too.
