This is the beta (version "Beta 1") of the 1997 game, Postal, developed by Running With Scissors.
It may or may not work for you. After a certain date (not long after the beta was released), every character on screen will catch on fire and die, and the game will lag out and probably crash. I'm fairly sure it's an intentional time limit on the software. Not sure if it can be worked around by changing the computer's date back a bit.
