i think bousozoku is on to something... 😀
is this process always running? if you restart your computer, and only launch the process viewer, does this still show up? there are still lots of apps that dont list their names properly in the pv list, but this looks like somehthing else. my suggestion would be to try to quit the process. if that does not work, log in as root and see if it's still there. that really is quite puzzling. you could also check your login items, but i doubt there would be anything in there of which you werent aware.
