ekrn.exe using 50% CPU

Question

Hello,

I have a big problem, ekrn is using 50% of my CPU but I don't know how to disable it or reduce this load.
I know it's an ESET process but even when I disable the protection, it remains at 50%

<config>Windows 7

Well... how much RAM do you have?  -- ¤¤¤¤¤¤¤¤¤¤ Pre_Scan_Concept ¤¤¤¤¤¤¤¤¤¤

truc34 · Answer

I have 2 GB ekrn.exe takes up 36 MB but 50% of my dual core.

and if you disable it, what is your CPU at?  -- ¤¤¤¤¤¤¤¤¤¤ Pre_Scan_Concept ¤¤¤¤¤¤¤¤¤¤

truc34 · Answer

I can't disable it, I have access denied even though I am an administrator  my total CPU usage is at 54%  so if I remove the 50% from ekrn.exe, that leaves me with 4%

g3n-h@ckm@n · Answer

I can't disable it...  LOL!!!  The protective antivirus that traps you!!!! No!!! I'm your antivirus, not some other one!!! Mwahahahaha!!!  ¤¤¤¤¤¤¤¤¤¤ Pre_Scan_Concept ¤¤¤¤¤¤¤¤¤¤

Attention !!! : this tool may be mistakenly detected as a virus
Attention !!! : this tool is powerful, strictly follow the instructions below

all "non-vital Windows" processes will be stopped, save your work.

Disable all your protections if possible, antivirus, sandbox, firewalls, etc....

download and save Pre_Scan on your desktop:

https://forums-fec.be/gen-hackman/Pre_Scan.exe

if the link does not work:

http://general-changelog-team.fr/fr/downloads/viewdownload/41-outils-de-gen-hackman/52-pre-scan
http://www.archive-host.com

Warning: There will be a desktop blackout during the scan --> do not panic.

once downloaded, run it, let it scan until "Pre_scan_date_and_time.txt" appears on the desktop.

If the tool is restarted multiple times, it will offer you a menu and since no option is requested, launch the "Kill" option

if the tool is blocked by the infection, use this version with the .pif extension:

https://forums-fec.be/gen-hackman/Pre_Scan.pif

if the tool detects a proxy and you haven't installed one, click on "remove proxy"

There may be a multitude of black windows flashing, let it work

Post Pre_Scan_date_and_time.txt that will appear on the desktop at the end of the scan

It is possible that the tool will restart your PC, let it do so

DO NOT POST IT ON THE FORUM!!! (it's too long)

Host the report on http://pjjoint.malekal.com then provide the link obtained in exchange on the forum where you are getting help

disable the antivirus, restart the tool, click on "Diag" and provide the link to the hosted report

and if I wanted to hack you, I wouldn't need these reports :)
but that's not my goal, I'm here to fight malware and not to be a part of it :)

truc34 · Answer

in fact, it's random, it's roughly 1 time out of 2 but I think there are no solutions.

truc34 · Answer

It's when he's updating that he uses 50%, but sometimes he gets stuck on an update because he can't find an internet connection (I'm using FreeWifi). I need to authenticate on FreeWifi, cancel the update search, and restart it. After that, it's fine.

See u in a big bullshit · Answer

Good evening, hello, anyway hi, I have read this entire post here and I'm a bit disoriented...  Yesterday, I noticed that my CPU was around 60% right from startup, I tried several things, I ran an ESET NOD32 antivirus scan then I was advised to buy Malwarebytes to see if there was any rootkit the scans resulted in the removal of a few "potentially dangerous" applications  I then rebooted and as nothing had changed and I was still around 60% CPU with no applications open except my ESET NOD32, I let it run until today  And it was today that I took note of this ekrn.exe which is consuming about 50% of resources. I also bought the ESET version. Even though I downloaded the antivirus software before entering my key to activate it (I was already a user on another PC and I had protected it very well with this software for 5 years... before giving it to a friend)  In your opinion, what should I do??
