I have the same issue with XP SP2. I have Eset installed on 45 workstations, and only one of them has this resource hog. Every morning when it is started, 99-100% system resources taken up for 6-10 minutes. However, when I reboot during this Ekrn problem, it works perfectly. I have uninstalled it, cleaned up windows files, and reinstalled it. Removed all Adv. Heuristic settings on all sections, and its still the same. AMD 3800+ 1.5 GB ram XP 32bit SP2 (tried SP3 RC - no difference) NOD32 AV 3.0.621 automatic real-time file protection disabled, and still the same results.
