Dungeon Fighter Online and Avast

I have been trying to get a game called Dungeon Fighter Online to run on my PC.

Every time I ran the game I got the error message, “AHNHS - error has occurred on the hacking prevention function. (Error Code SS204) The program will shut down.”

Once I press okay I get the second error message “AHNHS - _AhnHS_StopService error (Error Code = SP 301)”

I have uninstall Avast and the game runs okay, so I know that Avast is causing the game not to run.

From what I can tell the anti-hacking software HackShield Pro in the game thinks Avast is an hacking tool.

I am looking for suggestions to get Avast and my game to live together peacefully on my PC.
