This is more of a FYI for you
You can disable bit defender temp. to do this you have to start your PC in "SAFE" mode first and once you are already there, you have to open msconfig.exe. Select the "Services" tab and there, and only then, you will have the possibility to UN-tick the BitDefender services. Re start again in the normal way (not safe) and BD will be "turned OFF" When you want to "turn ON" BD again, simply reverse the procedure.
The problem is that you are not able to stop BD services because of the "auto" protection feature IF you are on the NORMAL state (not safe) of Windows OS.
