This is a critical component for Nero Burning ROM and should not be directly removed. Nero Burning ROM is a utility program created for the Windows platform, originally for authoring optical discs such as CDs and DVDs. The first version was released in 1997 and has been released through ten new versions ever since. Different versions of the software such as Nero Burning ROM Lite were released as cheaper alternatives with limited functionality and features. Nero Express was targeted at entry-level audiences. It showcased a friendlier interface making it much easier to use. 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 a pain, it can use 100% of CPU at times and slows the Comp down. Remove programme Nero Scout if possible
I have Nero 7 installed so I buy that it's part of that software. I've killed it in task manager many times with no adverse effects
Heavy CPU Usage on single core systems
Used by Nero disc writing etc. Use Anvir free or other task manager to make it ON DEMAND. Can also stop it when not in use. In Services.
