It's part of Nvidia update, essential for gaming, don't delete!
Used for Nvidia Update
Nvidia Updater - Der Prozess stellt dauernd Verbindung mit dem Internet her. Das ist größtenteils unnütz, da man manuell nach Updates suchen kann. Und Programme, die dauernd ihren Status mit einem Server abgleichen, können sehr leicht zur Rechner- und/oder Benutzerüberwachung benutzt werden. Dies ist aus Gründen des Schutzes der Privatsphäre problematisch.
Used a lot of CPU (+50%) for extended periods of time for no reason (I had just installed the latest stable version a few days ago, so there was no reason for an acutal update). I deleted the program and my computer works just fine. If you ever need to update NVIDIA drivers, you should do so manually, IMO
I just scanned all my daemonu.exe files with MalwareBytes and nothing suspicious was found. It is an NVIDIA updater file.

Best practices for resolving daemonu issues

A clean and tidy computer is the key requirement for avoiding problems with daemonu. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
