BitDefender consumes too much network

Problem is BitDefender's Products tried to download something while I playing online game. They hog all network bandwidth cause massive lag. I have to force end task but it keeps popup randomly. This is very annoying. Is there any method to disable, block, delete this.

-Game Profile is on

-Update rule is set to "Prompt before downloading"

-Autopilot is off

-Cannot block by firewall

-List of the programs that cause problem: vsserv.exe, bdwtxag.exe, DevMgmtDervice.exe, ProductAgentService.exe<-This one is the WORST
