Hi, by searching I saw people had this problem in years 2009 & 2020 too. BD tells to update the skype from 188.8.131.52 to latest version. My Skype is latest 184.108.40.206.
Do you have Skype installed through the Microsoft store, or have you downloaded normally from the skype website? Bitdefender only detects and warns about out of date versions for the normal version, not the Microsoft store one. As for the detection itself, the most likely cause are remnants from an older or different version of Skype.
