What is this, and where did you get it? It's not a standard part of any Windows OS that I know of. The name suggests some kind of disk utility, but why would that ever need to access the Internet? The fact that it reinstalled itself after a reboot is highly suspicious. Is your antivirus running and up to date? I suspect a virus or trojan not previously known by this filename.
