Some time ago I upgraded bitcoin v0.18 to v0.19.0.1.
I downloaded it from https://bitcoin.org/en/download (Mac OS version), but Bitdefender antivirus detected Bitcoin-Qt as a threat.
Is this just a "False Positive" Antivirus Problem?

Antivirus often falsely flag Bitcoin Core as malware because it contains mining logic.I downloaded it from https://bitcoin.org/en/download (Mac OS version), but Bitdefender antivirus detected Bitcoin-Qt as a threat.
