Installation to system When run, the worm copies creates a mutex 'ertglddfgd', copies itself to Windows System Directory with a filename picked from: smss.exe csrss.exe winlogon.exe services.exe
and sets a startup key for that file in System Registry: [HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Win32System]
