Hi 7days i have this problem as well , i wrote to malwarebytes and sent them a screen shot , as colif says it is part of windows defender , i mistakenly thought it was part of malwarebytes.
This is what i do , i have kaspersky anti virus so i dont have defender running in the background because once you have run defender it keeps the exe running in the back ground.
I do the odd scan with defender as it sometimes finds odd things that other software misses .
The best thing to do is do an occasional scan before you turn your pc off and turn defender off again before you shut the pc down.
