What does the Blizzard Agent.exe does and what is it?

What is Agent.exe ?
Agent.exe is a new tool, created by blizzard, to help you download faster updates and patches. It offers automatic peer-to-peer (p2p) connection between everyone who is currently downloading or uploading the update or patch which you are downloading.
The file is not hazardous to your computer. You can see that by checking the VirusTotal scan.

What is Agent.exe for?
It's needed by applications such as World of Warcraft and Diablo III to properly run. It makes connections to the official blizzard update servers and also to all of the peers which it discovers. This is why, if you do a netstat, you will see connections to Verizon and such.

How do I stop Agent.exe?
To stop this process, you can simply press CTRL+ALT+DEL and navigate to the Task manager, find the Proccesses Agent.exe*32 or Agent.exe*64 and press Del to close them.

Problems with Agent.exe

I've heard several people having problems with Agent.exe while trying to play WoW on a linux based OS with WineHG (yes, you can play mist of pandaria BETA with WineHG on linux, like Ubuntu, Debian, Fedora and so on). The trick is that you have to start Blizzard agent manually ($WINEPREFIX/drive_c/users/Public/Application\ Data/ --nohttpauth) before starting installation (wine "World of Warcraft Beta Setup.exe").

Another issue which was reported is that your computer might not be able to turn off right after you have played Diablo III Beta. The reason is that the agent.exe is still running and doesn't lets you automatically close it and shut down the computer. You will have to kill the process (as mentioned above) to fix this problem.
