Multiple brute force attacks on my RDP

Today I turned on RDP on my Windows 10 PC with Bitdefender Antivirus intalled, and I get a brute force alert from Bitdefender every minute. I was told on Microsoft forum (https://answers.microsoft.com/pl-pl/windows/forum/all/multiple-brute-force-attacks-on-my-rdp/f1f9e764-87ec-482f-962c-30bacb88277e) that it is a false positive. So I'm reporting it here. How can I stop the false positive alerts from showing themselves? Thanks.
