Virus Scanner is broken.

edited January 2017 in Protection


Today i tryed to scan my PC for viruses. first i tryed FULL SYSTEM SCAN, when i press run the scanner stuck on scanning  winrnr.dll and never move from that file.(look screenshot 1),when i start QUICK SYSTEM SCAN i get immediately screen of results of scan(screenshot 2). Only custom made scan is working. I run repair bitdefender, but that dont fix my problem. How to fix it? Is it update bug what broke scanner? Sorry for bad English. 

I will be very happy if you help me to fix.
