--- Comment #1 from Sebastian Lackner sebastian@fds-team.de --- These are indeed false positives, and I also tried to contact Bitdefender about it in the past. I just submitted another false positive report at https://www.bitdefender.com/submit. Hopefully they will be able to fix their detection.
It might also be possible to "obfuscate" the Wine code to avoid the detection, but it will probably then cause trouble with the next anti virus program. Unfortunately such heuristics are terribly unreliable...
