Help?

Hey guys some kid on combat arms said he was going to hack my computer and delete all my files. But is this really possible with just the username of a game? He pulled up some sort of info on me like my IP or something.
Here's a screenie of him "claiming" to have hacked my computer.
But nothing has changed?
