Hello,
today I tried to update from 4.4.1 to latest version, but during updating (via launcher), avast automatically detected RPCUtility file and removed that. Just want to let you know that something like this happens.
RPCUtility.exe
Path: Unreal Engine/Launcher/PatchStaging/UE_4.4Production-Windows/Install/Engine/Binaries/DotNET
File Size: 26408
Category: Infected File
Description: Win32:Evo-Gen [Susp]
I have same consistent problem with UnrealBuildTool build from source, it’s heuristic detection (thats why it has “[Susp]”) so it only looks like it might be virus but dont need to and most likely is not. If it’s false detection you can send it to Avast devlopers via quarantine menu as flase positive and with that they can improve there virus definition to avoid false positives.
Also to be 100% sure scan file with virustotal:
Whcih will scan file with multiple antiviruses, if its only Avast that rise alarm you can send it as false positive
