if your computer is not acting up in any way, i would not worry about it. it does not seem to list whether or not the process is running, so it may just be some random bit of junk floating around, and i'm fairly sure that the only way someone could log in to your computer would be through a valid user name, and not anonymously. it could be some daemon of another process that was improperly labled by the programmer and that just does not shut off until you restart.
