    Hi !

    I have a problem with my ESET Endpoint Antivirus 5.0.2122. The problem appears when I plug in an USB key in my computer. When I do that, the ekrn.exe use 100% of my CPU. But there is something strange.

    I have 2 VMware View Workstation on Windows 7 64bit. This is a VDI solution. I use Samsung Thin client with Terradici chip.

    In the first workstation, when I plugged an USB key, a message from ESET appaears (http://kb.eset.com/library/ESET/KB Team Only/SOLN2882/Pop-up Example.png). I can browse my key instantly. The CPU is OK.

    In the second workstation, when I plugged an USB bey, there is no message from ESET. I can not browse my key and the ekrn.exe use 100% of my CPU.

    The two workstation have absolutely the same configuration and they have the same policy from ERA too.

    I don't why this is appening.. I have try a lot of things with no succes.

    Do you have any idea?

    The latest version of Endpoint products is 5.0.2126 which has Device control disabled by default and also addresses certain issues related to it. Please confirm or deny whether the issue persist after upgrade.

    Unfortunately, the Device control settings are not visible in your screen shot (it's below Removable media). If it's enabled, try disabling it and restarting the computer. Otherwise try disabling real-time protection (for a test only) and see if it makes a difference. Let us know about your findings.

    Hi,

    The device control is desactived (integration system not checked) -> still the same issue.

    Hips enabled : No -> still the same issue
    Enable ESET Endpoint Security Self Defense : No -> still the same issue

    If we try disabling real-time protection, there is no problem.

    We have use Procmon when we have this bug. We can see :

    There is a lot of the same key..

    We have try to exclude the folder of VMware -> Still the same issue.

    All the test is on ESET Endpoint Antivirus 5.0.2126.3

    This looks like a known issue with VMware when the USB hub reports all 255 USB ports.
