ekrn.exe causing 100% Cpu usage when viewing shared folders on networked computers.

Let's say your PC can immediately access the content on the shared folder (sometimes it can not) and let's say that the content of the shared folder has a number of executables and/or compressed files (unless you can provide more details), then this post can be helpful to you: (ESS RC1 On Demand Scan issue) http://www.wilderssecurity.com/showthread.php?t=186803.

Here's part of what I wrote:
-{ Quote: "Depending on how you configured the profile(s) your using for the on-demand scan, it could take alot longer compared to the current v2.7.39 (due to, hopefully, more advanced/powerful scanning engine). The usual settings that can affect scanning speeds are Advanced Heuristics, Potentially unwanted/unsafe apps, Archives, Self-extracting archives, and Runtime packers." }-
Just disregard references to profiles and change the words on-demand to Real-time file system protection. Also make sure that the one's you tweak are in the ThreatSense engine parameter setup and not in the additional parameters.

Ooppsss... I failed to notice the screenshot. My bad :-[ .

Try unchecking Advanced Heuristics as it has a greater impact on performance (and effectiveness in detecting virus/trojan/malware/etc.) than Potentially unwated/unsafe apps... i think ;) .

hey thanks for your reply, freesurfer, turning adv. Heuristics off under ThreatSense engine parameter setup solved it.
