Libre Office 3.6.1 Help and WS.Reputation.1

I can't install the help package from the new LibreOffice Release (3.6.1) LibO_3.6.1_Win_x86_helppack_de.msi, cause NAV deletes it with a "WS.Reputation.1" found message.

 

The installer for the main program is fine with NAV.

 

I downloaded the Installer directly from LO: http://www.libreoffice.org/download/

 

Frankly I don't believe that the official LibreOffice installer is infected.

 

System: Win7 64bit, German Version
