Computer shuts down with Message: System shutdown initiated by NT Authority/system System must restart because DCOM server process launcher terminated

[LS SteveJ 0]

Symptom

 

During an Ad-Aware scan, your computer may shutdown with an error message "System shutdown initiated by NT Authority/system System must restart because DCOM server process launcher terminated unexpectedly"

 

Cause

 

This is most probably caused by a malware known as KILL-AV (detected by Ad-Aware as Win32.Trojan.KillAV), which attempts to thwart Anti-Spyware and Anti-Virus programs by restarting the computer before a scan and removal is complete.

 

Solution

 

To remove this malware. Scan with Ad-Aware. When the box pops up containing the error "System shutdown initiated by NT Authority/system System must restart because DCOM server process launcher terminated unexpectedly", cancel the scan immediately and click next. Quarantine / Remove any Win32.Trojan.KillAV objects that are found at this point. Let the computer restart and the malware file should be removed after reboot. Perform another Ad-Aware scan to see if anything is left
