Had this same problem with the 2012 version.  I really would like to not have this product slow down my start up time so significantly.
This application took longer than usual to start up, resulting in a performance degradation in the system startup process: 
     File Name		:	vsserv.exe
     Friendly Name		:	Bitdefender Security Service
     Version		:	16.16.0.1341 95224
     Total Time		:	5179ms
     Degradation Time	:	2679ms
