What is NMBgMonitor.exe?

The genuine NMBgMonitor.exe file is a software component of Nero Scout by Nero.
NMBgMonitor.exe is an executable file that is part of Nero Scout, an indexing service that catalogues media files on the system. This program keeps track of changes made to files and folders on the computer and automatically indexes any new files. This is a critical component for Nero Scout and should not be directly removed. Nero Scout comes bundled with the Nero Suite. The program keeps a record of media files such as photos, videos and music files, making them faster to search. The indexing service has been known to slow down computers and many users choose to disable Nero Scout entirely. In the newer version of Windows, Microsoft has done away with indexing altogether making this program obsolete. Nero is a German software developer best known for their flagship disc burning software program, the Nero Suite. Richard Lesser founded the company in 1995 as Ahead Software GmbH but the company changed their name to Nero in 2005. Nero became quite popular after many OEMs (original equipment manufacturers) decided to bundle the suite with their hardware products. Nero is headquartered in Karlsruhe, Germany.

It is an absolutely useless and resourcestealing process of Nero.
Takes too much memory. 170,700 K
NmBgMonitor.exe obviously indexes all multimedia content on your computer and if you have lots of it, this process can bring your computer down to its knees. On my computer this proccess eats up to 1.5 GB of Virtual memory, and 380 MB of RAM, so it is a real disaster and computer may stop responding because of it. I recommend to kill that proccess.
