We now got a couple of threads on this topic, as it seems this is affecting several Bitdefender users.
Microsoft owns the domain, and the SSL certificate recently expired, but there is no danger of malware or harm to the devices. This type of notification is triggered by the Online Threat Prevention module whenever the website you are trying to access doesn't have an SSL certificate (HTTPS) and it's not safe to access, and the alert is also triggered when you try to visit a secured website (HTTPS) with an invalid security certificate and this is what happens here actually.
I understand that several community members have raised concerns about the certificate issue on Microsoft forums, and most probably they are working on a resolution and will release a fix soon.
For further information, you can also contact the Microsoft Support Team:
I hope this gets resolved asap.
