Hopefully someone can explain this:

I’ve had 1.0.3.9 installed for about 1 month.

Today, I got an upgrade notification, went to install, and Bitdefender went scorched earth on it.

’Advanced Threat Defense

You must restart your device to finalize the cleaning process.
Bitdefender detected potentially malicious behavior and blocked all applications involved.
Detection ID: SuspiciousBehavior.B7B150B04A1374AB’

So I scanned both 1.0.4.0 and 1.0.3.9 installers with some online tools…

Coodesker-x64_1.0.4.0.exe (latest file):

Coodesker-x64_1.0.3.9.exe (one I had installed):

https://opentip.kaspersky.com/454FD6988590181267FA4490A72047BB0257B3EAA5A9E10B1291DB45B9AE41A4/results (shows as safe)

The virus total and hybrid analysis could be false positives for 1.0.3.9 as it installed OK etc, but both Kaspersky and Bitdefender and detecting on 1.0.4.0.
