As said, then i don't know about BitDefender. But i will assume it is definitely for this version at least.
Also as i wrote, then if it's reported, then BitDefender will be updated to not see it as a virus, and thus not block it.
But when a new version of Arturia application arrive, then it perhaps can happen again. It only happens sometimes. It also have to do with BitDefenders antivirus definitions.
Beside it's annoying and i think Arturia should look at what coarses this, then there should be nothing to worry about. But if you worry and wan't to be completely certain that Arturia software is'nt a virus, then wait to install untill BitDefender no longer block it. Just report the issue to BitDefender and wait for green light. But you can read about what to do and what happens in BitDefender instructions.
