I want to use messenger more than 1 user
Wenn im Ordner Programm\Files\ZDFnachrichtenkurier mit ZDF Logo vor Dateinamen, dann harmlos. Kann sich jedoch aufhängen und mal 50% CPU usage zeigen.
Messenger.exe is common cover name for NSIS/TrojanDownloader.Agent.NFB trojan (and few others).

it is impossible to remove. I think it is stored in zip file which something automatically makes it unzip on startup. I found a process using ccleaner directing messenger.exe to run. I run Norton & kaspersky and both get negatives!

Best practices for resolving Messenger issues

A clean and tidy computer is the key requirement for avoiding problems with Messenger. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

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. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Messenger.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
