Most of the time it's just a cover to infect peoples PC's with viruses, saying "Of course your Anti-Virus will pick it up and say it's a threat" by that they mean since it's a hack, it'll have some sort of file the Anti-Virus will pick up.. generally it's just a trojan in it. These hacks are pointless, they ruin the game and chances are, ruin your account.

So have fun!
