I've noticed this for quite a while but it hasn't really bothered me so much till I updated my Logitech setpoint drivers for my keyboard and mouse. Every single time I open up my setpoint options or try to update anything dealing with any of my 4 Logitech products, ekrn.exe goes crazy and uses up to 99% of my CPU. Nod has already allowed 4 trojans pass by, luckily my other software caught it. It is horrible against spyware or adware. But I would at least expect it not to flip out every time I open a little configuration window or my bluetooth settings from logitech. Does anyone know a fix to this.
