Since updating to Avast 6.0.1203, the only way I can play Left 4 Dead 2 is if I turn my Avast protection off. Prior to this update, Left 4 Dead 2 was working fine.
Upon launching Left 4 Dead 2, I would get stuck at a "Completing installation... 1%" message until an "Incomplete Installation (#)" error would appear. The only way I could get passed the installation % message and launch the game was to disable Avast. Since the initial disabling of Avast, I no longer receive the "Completing installation... 1%" message or the "Incomplete Installation (#)" error.
While Playing With Avast On, Left 4 Dead 2 would immediately freeze upon load of a game mode and sound would get stuck in an infinite loop.
While Playing With Avast Off, Left 4 Dead 2 would run fine.
Although turning Avast off is an option, I really would prefer to have my Avast protection on while playing the game.
There are other people who also have this problem. Here is a link.
