Is it possible for Webroot to produce false positives on the malware W32.Adware.Gen?

I am a software developer, writing java code for distribution to my companies customers boxes.
 
To convert our executable jar files to Windows executable files, we download launch4j-3.8-win32.exe from the SourceForge website at:  http://sourceforge.net/projects/launch4j/files/launch4j-3/3.8/
 
We scan the launch4j-3..8-win32.exe file with Webroot and Webroot reports no problems.
 
We then open launch4j-3.8-win32.exe, and during installation, we see Webroot scan errors which indicate that the file launch4jc.exe contains the malware W32.Adware.Gen.
 
So, we are faced with the following questions:
 
1.  Does the launch4j-3.8-win32.exe file come from SourceForge with the malware already attached?
2.  Or, does my development box have the malware, and the malware attaches itself to Launch4j during the install?
3.  Or, are we seeing a false positive for W32.Adware.Gen in the Webroot scan?
 
Until we know what is really happening on the box, we can't risk deploying our app to our customer boxes.
