My firewall (kerio 2.5) reported that nod32krn.exe had changed when I reboot this morning -- though I have not turned on this PC for about a week. So about a week ago there must've been an update to the nod32 kernel, but I cannot find anything online mentioning this. The logs just say "Virus signature database has been updated" and nothing about the kernel. The same thing happened maybe a month or two ago (but I let it pass). Is this valid (or is something else changing my .exe)? Win98SE nod32 v2.7 2.70.32 Thanks.
