Hacks detection, Headset problem, disconnect error

1. Headset ( Creative Fatality ): When I pugging my headphones by USB, the Game isn't staring. There is a small black centered window on the screen. Headphones works only when I plugging it without USB, but then I have completely different sound and basically I don't hear much. Maybe on TD thats not a problem, but on S&D this is a problem for me.
2. When I playing sometimes pops up window " Hack tool has been detected: 0:4:0:0" and The Game ends when I click "OK". Then I have to wait 3 minutes and I can start play again. That is very annoying especially when I'm in game on last round. I have no programs turned on in background. What the reason of that?
3. Ping (problem to speculate , I have wireless internet) , in average 3 times per day pops up a communicate " Disconnect form host ", when I have ping 30-35. 10 seconds of wating for another error and then 3 minutes waiting for lunch game again, sometimes its without ending the game, then It takes me to lobby.

All of those problems start to appear since past 2 weeks, I had no such problems before.
