Help me find a movie

I watched this movie on TV, what I remember is that a group of friends sort of rents a house and the main character finds something like don't look or don't listen in the bedside table, which I don't remember exactly. Then in the morning they find huge scratches on the facade of the house and they begin to see something that the main character is not driving in the library to find out something about this, he finds a story about how a man shot the whole family except his wife and himself, including, because of his beliefs, his girlfriend gets hit by a train, then he finds this surviving widow and she says that there is no way to get rid of this and there is only 1 way out, it is to eliminate all carriers and he gives him a gun, but he understands that the visions should just be ignored and goes to tell about it, but on the way he knocks down a library worker who gave him those books in the library and she, too, was roughly infected with this ghost and goes out on the road and he knocks her down, then he runs home and burns the whole house there and he shoots himself, his friend sees it all with his daughter and
