I am one of the people affected by the NOD32 bug where ekrn.exe uses up all CPU resources to the extent that the system is unusable. I am curious how many other forum participants have been affected. Other than removing and reinstalling (which did not help), I have not received any suggestions from ESET support. I suspect that they are overwhelmed by other users with similar problems as it is taking them unusually long to respond. I had already tried deleting the update cache, etc. that some of the threads here had suggested. I would also appreciate people's recommendations about other AV software than NOD32. After now 2 weeks of trouble, I have reached the point that I need to think about other products. This is a serious problem and ESET better wake up. It may not affect every individual user, but with bugs like this one, any potential corporate client should think twice before rendering a subset of their workstations useless in this manner. Thanks in advance.
