So has the problem been solved?

You’re asking in the wrong location.

I would suggest monitoring that landave’s blog link.

Also make note of the very last point.

Thanks & Acknowledgements

I want to thank the Bitdefender team for fixing all reported bugs. In addition, I want to thank Alex Balan, Octavian Guzu, and Marius Gherghinoiu for providing me with regular status updates.

Given that comment I would have to wonder if they haven’t been resolved.
