system file check found errors but, can't repair it

and Bitdefender & MBAM didn't found any threads

most strange thing is Bitdefender can't update itself... i've fine internet connection, and update are fine early, but now, it can't...

what is the reason? driver? system file damaged? or something else?

how to solve/fix this? thanks
