Incorporating.....

I've got a question about incorporating... I've got a programming biz in South Carolina that is incorporated. I've heard a "rumor" that another biz is trying to incorporate under my name but adding a .com to the name. An example biz name is abc and they want to inc. under abc.com. Is this legal? I'm going to contact an attorney next week but was wondering if anyone had any experience with this.

Thanks...
Ron
