Yes. Folding At Home, run out of Stanford University, is a massively parallel computing project doing basic research on protein folding as it relates to several dread diseases. They download work for your computer to do, your computer uploads the results to them. It's safe, there's never been a virus or trojan transmitted.
There can't be any Trojans, it's from Stanford not USC
. It only costs you for the electricity to run your computer and it definitely extends the lifespan of its power button.
All in all, an easy way to do something good and engage in friendly competition. Go to
