DarkComet

So I play a game just like Runscape. I have DC working with no-ip, made my first bug. I tried uploading my bug to a "share site" but they recognized it as virus and wouldn't let me. I tried putting into Email and Email provider exposed it as virus. I notice the people in my game that are doing this have a link they post in chat for people to open>download>HACKED.. Any advice that can help me out would be great!
