I have been mining Veruscoin for a little while...very recently a major player shifted completely the profitability:

330 GH/s!!!! That's 100K computers!!!!
Is there a new FGPA/ASIC available? Or is it someone who somehow infected thousands of computers and mining without them knowing?

This is a total mystery for me.
