My one was located in Program Files, i searched it and it says it was a virus, so i disabled it
It is an annoying error and virus! It comes with ITM or Sigmatel Audio, just uninstall it!
It's nothing but a audio drvier,not dangerous at all
it is an audio application and can be ended, It used a lot of CPU of startup.
it caused an expection / bluescreen on my HP ProBook 650b during startup , I deinstalled the sounddrivers, now the system crashed somewhere else ... I can not blame STacSV.exe for being the problem.
  Gerd K.
