I'm trying to remember the name of this scary movie?!

It starts off with the dad coming home from work and he's carrying a briefcase!. He enters the front door he turns the corner into the living room his wife and two daughters are dead on the couch, he runs to his son's room opens the door just as the son lays down on a knife which is in the center of some satanic altar!. Then the camera follows his son's soul down into hell!.

I can't remember anything else from the movie but I hope that's enough that someone could tell me the name!.Www@Enter-QA@Com
