Hello,   
I warn you not to use Dr.Web 9 currently in BF4. 
I was a victim of the ban (Violation (aimbot) # 50856 since the installation of Dr.Web Security Space 9. 
  
Several topics demonstrate this false positive:

Other contacts have confirmed this ban with Dr.Web 9. 
There is a conflict between Dr.Web version 9 and PunkBuster. 
  
I contacted by email EvenBalance, they analyze the problem. I am waiting for their response. 
  
Are there other users of Dr.Web ? 
  
Sorry for my english, I'm using a translator.
