After installation on a Windows XP machine and upon attempted first (and subsequent) opening of Kompozer, Novatix's CyberHawk threat analysis program pauses the open process and notifies the user that the program is a high risk, as follows:
Application Name: Nvu - KOMPOZER.EXE
This program is attempting to modify your computer so that another computer can access it.
This is version 188.8.131.52 of Cyberhawk and the installation package from which the Komposer was installed was the kompozer-077-win32.exe installer.
I don't know about anyone else but in today's enviornoment, I'm reluctant to proceed with opening Kompozer based on this threat analysis and have not done so.
Though you might want to know.
