If its a problem with a hackshield....well, Avast! has had such before, and so have other AV vendors. Since anti-cheats are basically rootkits, they do have a hard time getting along. What specific anti-cheat are you speaking of?
what do you mean?
I don't know what part you are asking about. But to rephrase/elaborate,
1: Anti-cheat programs for online play are typically rootkits. You might jump and think that is bad, since rootkits are always associated with infections. But anti-cheats are and example of a friendly rootkit. But since they operate just like their malicious counterparts, and AV companies are always trying to fight rootkits, they often have conflicted.
2: The name of the particular anti-cheat (there are different brands, AhnLab is one example) that the game uses would help. This is something you would have to ask the DragonNest people.
That said, I would personally never install one of these just to play a game (and I am also quite the game junkie
), because it is a program operating with higher privileges than anyone is supposed to have under Windows, the potential problems that could arise from that have always kept me away.
