What is mbbservice.exe?

The genuine mbbservice.exe file is a software component of Mobile HiLink Broadband Background Controller Service by Huawei Technologies Co., Ltd..
This Windows service is automatically installed by Huawei 3G/LTE USB broadband modems and used to automatically connect to the local cellular network. It can be uninstalled via "Uninstall or Change a Program" in the Control Panel by selecting "Mobile Broadband HL Service." For better system startup time its loading can be delayed under "Services." It tends to install under "C:\Program Files" in a parent subfolder ("\MobileBRServ\") that may have improperly secured permissions allowing all users to create and append files, which a local attacker may exploit to gain full System level access; Huawei has verified this issue. Huawei, a mainland Chinese company in Shenzhen, Guangdong province, supplies mobile broadband Internet service and associated devices to nearly one-third of the world's population and has reputed ties to China's military, causing some governments to ban use of its products for official communications.

Huawei mobile internet stick(Hlink E3131) using same named file, while building internet connection to your computer.

It can use processor time intermittently even when the mobile device is not present on the system.

In my case mbbservice slowed down the internet connection giving problem with the sound card. For instance was Skype working badly and got interrupted repeatedly. Sound dropped even while watching YouTube. Removing mobile Broadband HL Service solved the problem. Momentarily I have a poor Internet connection. With better bandwidth this program may not cause any problem.

I don't think it is dangerous, but it used considerable resources with my customised Win 7 installation. I disabled it in Windows Services. The drivers still load, and I can access the settings by going to the Hlink page.
