Blizzard, the gaming company that makes WoW, SC and Hearthstone uses battle.net.exe and agent.exe.
When I close the battle.net application and don't have any games open, agent.exe runs in the background. If I end agent.exe's process in task manager, it reboots and continues running. There's no way to shut it down. If I suspend process for agent.exe in Windows Resource Monitor, the battle.net launcher and games don't work until I unsuspend it.
24 hours a day, agent.exe is sending data from my computer to Blizzard. It sends about 350 bytes per second. It sends data even if I don't have any Blizzard applications open. If I have Blizzard applications open, battle.net.exe sends about 350 bytes per second instead of agent.exe.
What data is Blizzard sending from my computer over the network? Why does it need to collect this data 24/7? Is this some serious spyware that I should be seriously concerned about and should consider uninstalling the application? Or is it just sending data about its games back to its servers?
I tried searching about this issue online but found that there weren't many people talking about this. It seems that this might be happening to everyone who uses Blizzard software, but I'm not sure.
