Trojan or false positive? F-Secure blocks installation

While installing UE 4.17.2 my antivirus (F-Secure) blocks a file called game-html5-shipping.js for being a trojan thus failing the installation.

Should I just disable my antivirus while I install or is there even the slightest chance that somehow it’s a real trojan?

I think I got The same alert today with F-Secure SAFE… Harmful file “UE4Game-HTML5-Shipping.js” removed

Reason: Trojan:W32/Generic.50dfd23aab!Online, location
…Epic Games\4.17.z0ZGq\Install\Engine\Binaries\HTML5\UE4Game-HTML5-Shipping.js

Would really like to know.
