    Which is what I put down to Eset scanning the file as it doesn't do it without Eset installed/enabled

    Whats up and how do I fix it?

    cheers

    I have been having this issue for a while. Had it in Vista and now in Windows 7. I have browser.download.manager.scanWhenDone set to false. Windows 7 x64 is up to date and running the latest version of NOD 32 64 bit version. Even for small files, it freezes for a long period of time and erkn.exe is using 25-50% of the cpu.

    Hello amrinders87,

    Do you use any other browsers and if so, do they exhibit the same behavior?

    Yes. I tried it in the latest version of Google Chrome 3. When the download percentage reached 100%, the download manager froze and ekrn.exe process jumped to 25%.

    when you download something from your browser, it goes into a temp file until the download is done, then the file is created.The anti-virus is doing it's job, by scanning the temp file before it's created.the delay should only be a few seconds, depending on the file size, sometimes longer but it's still normal what your seeing here.

    Could you give us an example of a url of such a file so that we could try to replicate it with the very same file?

    I'm using IE8, Windows 7 x64 RTM, and ESET EAVBE 4.0.437.

    That file took a massive 47 seconds to scan, during which ekrn.exe shot up to 50% and my laptop cooling fan went into hyperdrive mode.

    And it's only 4MB :)

    Definitely something in this file that ekrn.exe doesn't like.

    I guess you guys have runtime packers and advanced heuristics checked for real-time file system protection ? it tells you there can be a performance hit while having these checked, try to download it without those checked in the real-time advanced threatsense section.

    They are off for real-time but on for Web access protection. I guess I can disable them and see if it improves. Thanks.

    Nah, I was just trotting out the 'Over 9000!' internet meme. :p I've seen the whitelist mentioned a few times and was curious about the numbers, that's all. :)
