System Infection

When the worm enters the system it creates a copy of itself in the Windows Directory as 'avserve3.exe'. This copy is added to the Registry as

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
  "avserve3.exe" = "%WinDir%\avserve3.exe"

It creates mutexes named 'PinaasoSky' and 'Jobaka3'.
