Older versions of Nero (specifically Nero 7, 8, and 9) included a file named avcore.dll or, in some patch distributions, avcore.exe . This file handles audio-video core processing for Nero Vision (video editing) and Nero Burning ROM. If you have a Nero product installed from 2008–2015, this process might appear in the background.

While it is a critical part of the Arcserve ecosystem, users often encounter it in their Task Manager and wonder if it is safe or why it is consuming high CPU resources. What is the purpose of avcore.exe?
