Norton 360 recognize the hbolauncher.exe as a virus (SONAR.Heuristic.120) and deletes it.

I've been down this road before, some Antivirus software reporting my .net application as a some form of virus/trojan, when it's NOT.
The heuristic part means that Norton 360 thinks it's a virus based on how the software is written, but it's not.
Here's what I found when searching for SONAR.Heuristic.120 on the Norton support forum:

"Heuristics is a feature which uses a lot of artificial intelligence techniques for detecting malware in the system, rather than depending on signatures.
This advanced feature can cause a lot trouble in the developer environment by reporting false positives. This false positives may be also because of the programming style or libraries used.

Mostly the Norton series of products by Symantec is consumer / house hold intended, where most users like it set it and forget.
house hold line, which aims for simplicity and set it - forget it functionality."

I can assure you that I take this very seriously and I've stopped all download links for now.

I've also scanned the HboLauncher.exe application with www.virustotal.com which has 54 different antivirus engines and none of them found anything wrong with the HboLauncher.exe.

I know that it is probably a false alarm but I thought to inform you about it.
Yes, it should be clean:
