Need Help In Running A Game!

Everytime I try to run my game "Mafia" it would take me to my main desktop and give me a message like this:

Protection Error:
A debugger is detected! Please close it and restart windows!

Whats a debugger?
How do I close it!

Well to answer your question, a debugger is an application that runs with a program to detect bugs in the program you are running, but apart from that, I can't really help you with your problem. What are your processes?
