    I have to join in. Also, the same problem. Happens before windows update, and still happening after the update.

    And it seems this is not the only problem. If I tried to do a manual scan, it's always stuck at scanning operating memory (someone already opened up another thread for this one).

    Hope there's a solution soon, and it's just a bug, not a virus.


    Windows 7 64 bit Ultimate Edition EN
    4.2.40.0 / 5358 (20100811)

    Update: The latest update (5361) seems to have fixed it.

    Give the guys at ESET a chance. The patches only came out yesterday, and they don't get the patches any quicker than you do. So all these comments "fix it soon" or "why no statement from ESET" are a bit harse IMHO.

    The same happening here.
    I only noticed it after the latest virus sig update 5358. In fact the thing that first alerted me was my CPU idle temperature jumping up by 6º C for no reason.
    Looking at task manager I saw that ekrn was using 25% of CPU resources.

    Running Windows 7 x64, NOD32 4.2.58.3.

    Same issue after updating to 5358, have called ESET who said they are unaware of any issues.

    Eset will surely solve this issue...
    Just be patient and disable startup scan for now...

    I've had the startup scan running for hours now on my Exchange Server. Looks like ekrn.exe has brought the Exchange Server to its knees twice this morning. ekrn.exe is sitting at a constant 50% CPU utilization. This all started after an update at 3:22 am to Version 5357. Not real happy right now!

    I tried the CrashOnCtrlScroll method and although my comp did crash it didn't do a memory dump, the screen just went black. So, sorry to say I can't help you with a crash dump.

    I'm running Win7 64-bit (updated with all patches released, incl those that came yesterday) together with Nod32 version 4.2.58.3 and virus-db 5358 and have the same problem with the startup scan not finishing. Turning off Anti-stealth helps though.

    Add my name to the list.

    4.0.424.0/5358

    Windows 7/ i7 920

    Core 1 permanently @ 86%


    Just Updated to 64 bit (version: 4.2.58.3 / 5359) with same results.

    Also, starting a scan produces the same stuck result - stuck scanning Operating Memory

    Eset is aware of the issue and working on a fix. Temp fix that we were given is as follows.

    -Turn off scanning of memory in startup scanner

    -Turn off Antistealth (AS)

    As we discussed, these changes will require a reboot of the ESET server.

    We have been trying to reproduce this problem on fully updated Win7 x64 systems to no avail.

    Anyways, we're about to revert the Anti-Stealth module to the previous version shortly (in fact, it will show as build 1021). A computer restart will be required for the module to get loaded. The Anti-Stealth module 1020 will remain on pre-release servers as it had been there for a couple of weeks without any problems reported by any of dozens of thousands users who downloaded it.

    Please if you can and are able to reproduce the problem, enable pre-release updates, reproduce the problem and generate a complete memory dump per the instructions here. When you have the dump ready, let me know so that I can provide you with further instructions.
    We appreciate your cooperation in advance.

    Updated to virus definitions 5359, "download prerelease updates" is NOT ticked. Startup Scan runs with an end, but, there is no flashing in the tray icon. I only see the date of finishing the startup scan under tools -> scheduler.

    Yes, ESET shows anti-stealth module version 1021 with 5359 update. (without pre-release updates disabled)

    I'm sorry if I ask something stupid... I have updated my virus definition to v. 5359, with the pre-release option unticked. The start up scan is still going and it's not stopping... Do I need to restart my computer? Or should I tick the pre-release option in order to fix this?

    Thank you,

    Updated to 5359 without prerelease updates sucessfully. Eset shows anti-stealth module 1021. But, as I said, there is no flashing, when a start up scan is in progress. So what brings, if "prelease updates" is ticked. Flashing?

    EDIT: Ok sorry, forget about the flashing. I created a new task for startup scan, which scans "all registered files" (should take a little bit longer) and yes, flashing is shown.

    But still the question: What brings if "enable prerelease updates" is ticked especially for this problem.

    Last but not least: THANKS Eset, for the fast response and help, nice job!!

    gn8 everybody!

    Enabling pre-release updates will dowload the problematic Anti-Stealth module 1020 which improves rootkit protection. Our goal is to pinpoint the issue and provide a fixed version of the module for testing as soon as possible. Whoever can generate complete memory dumps from the problematic state, please do so and provide it to ESET (drop me a PM once you have a dump ready).
    The weird thing is that tens of thousands of users had downloaded module 1020 from pre-release servers in recent weeks and nobody reported issues that emerged after today's update.

    Unfortunately, there was no indication that the Anti-stealth module could be the culprit. There's a sticky thread about reporting issues, one of the steps is to confirm or deny that the problem persists with default settings. Now I've added another step - to try disabling Anti-spam and Self-defense, one at a time and restarting the computer. This will surely help us narrow down potential issues in the future.
