Okay, here's your breakdown. You have at least one virus. I also notice you have mcafee virus scanner. Do you update it regularly? Because it won't do you any good if you don't update it.
To stop these processes, hit ctrl, alt, delete, and find them, there should be a button that says "exit' or "kill" or "stop" or something like that. Or you maybe can right-click and choose stop or something like that.
