I wouldn't be surprised if you have a virus on your PC now. You sound like you're willing to download anything from anywhere. Be careful. As your English isn't that great I assume you aren't in the US. It's also possible you are playing Combat Arms EU and these hacks are for Combat Arms NA.

Yes you do. You can start by looking here:
