Auf jeden Fall wird man über Systemänderungen informiert, besser als wenn man nur kostenlose Firewall & Antiviren-Software einsetzt

Calls itself "Windows Defender Command Line Utility" is m$ signed and resides in the defender directory. I have no idea though why it is running all the time, never started it, and only recently it was there (maybe after latest vista service pack?)

Verbindet sich bei mir alle paar Minuten ins Internet. Keine Ahnung warum. Dabei werden keine Updates überprüft. Wird MmN nicht bzw nur temporär benötigt, da der Service Win Defender bzw MS Security Essentials auch ohne ihn laufen.

Best practices for resolving MpCmdRun issues

A clean and tidy computer is the key requirement for avoiding problems with MpCmdRun. 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 doing a repair of your installation, or in the case of Windows 8, 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 MpCmdRun.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.
