This afternoon I was in a situation where nod32krn was using 98-100 percent of the cpu, immensely slowing down the system. I do not know what I was doing to cause that except I was download some files thru Firefox but it had been at least ten or fifteen minutes since last download. I waited for NOD to clear itself but it never did so I rebooted the pc? All seems ok now. Is it normal for NOD32krn to occasionally get stuck in some mode where it hogs the CPU time? If it happens again is there a way I can find out what is causing that to happen? It is a regular xp system and I'm running spysweeper and zone alarm in conjunction but only the NOD program was hogging the CPU and I had closed Firefox too.
