Ooohhh... That really doesn't look good. Read over those links, take your system offline if you care about it...
It appears, to me, to have a UID of 0. This is root's uid. If a user has a uid of 0 the user is "seen" by your system as root himself (which is bad).
If you don't have a root password, create one. If you have one, change it. Read those links above, and uh, good luck
