Mystery task hogging CPU time

I've recently noticed a slowdown in performance of my G4. I also noticed the appearance of the Core_65.ex entry in the top terminal app. Here is a screen dump:

Does anyone have any idea what this Core_65.ex might be, and why it is taking so much of my CPU time?
 
testuser,
I killed it and it turned out to be the number crunching end of Folding@home - the protien folding distributed computing project. I had this launching on startup and running in the background, but now I think I'll only run it when I'm not working. Thanks
