Environment

• JRuby version: 9.2.4.0
• Operating system: macOS 10.14.1
• AntiVirus: BitDefender 7.2.1.6
• ruby installer: rvm 1.29.4

Expected Behavior

• Installing a JRuby release must not raise warnings/alerts in security related monitoring
• the command to install ruby in a terminal: rvm install jruby-9.2.4.0
• setup of jruby environment successful and operational

Actual Behavior

• BitDefender antivirus reports a Trojan.GenericKD.40744760 in jrubyw.exe and removed it from my filesystem.
• As the file is a Windows wrapper executable to host a JVM, it is of no use on macOS and no harm is made on my system.

Remarks

Although, I am not affected during development, I will be unable to deploy this into a production environment at my clients. Any security related incident, will void the affected version from being deployable.
