    I have isolated the problem to NOD32 AV, goodbye

    I have been using ESET product as my sole AV for more than 3 years,
    I have 4 month left to my update yet I'm moving over,

    Main reason, I've no time to loose and Don't care the slightest to know why would an AV (NOT A FIREWALL) install drivers that react to transfers on my NICs.


    Ps: I use comodo as my FW (disabled)

    I know you said you don't have time for this, but could it be something to do with:

    1. Email Client Protection?
    2. Web Access Protection?
    3. Protocol Filtering?

    Do you have time to look at Advanced Options or have you already decided to look for an AV that makes all its own decisions?

    What exactly does "using network connection" mean? Do you notice the problem when copying files over network, when downloading files from the web or when simply browsing the web? I wonder if disabling HTTP checking the main setup (F5) make a difference.

    I can notice some 10% kernel usage with only utorrent at 300k/s but I was talking about local gigabit ethernet transfer that would spike red to 2 cpu (50%) max at sometime 2mbps And on a fresh start max at 20mBps instead of 56MBs if I uninstall nod32, wich I did many times.

    (Quad 3.6ghz)

    I've uninstalled for good, may not try installing again,

    I can't isolate component of nod32 or windows that cause the trouble.

    1. It is definitely network transfer related, and I don't want my AV to filter that.

    2. It's as if the driver is still filtering even if disabled in eset settings



    I'll just copy where I stopped. for the record.
    ,,,
    using latest version on Win7 x64

    It is not DPC it's just System kernel that would 100%
    I removing all I could in the advanced settings and rebooted that seemed to have helped, but not at all, this morning I can now confirm the problem only get worst overtime, transfer maxing out at ~150k/s (over gigabit) and mouse doing 1fps.

    transfering = high DPC this time

    All firewall are disabled, nod32 is all off, and
    IPsec Policy Agent service is stopped

    Stopping the Base Filtering Engine service will also stop these services.
    epfwwfpr
    so removed this driver manually and rebooted
    epfwwfpr Driver is not present in device manager
    still can't kill Base Filtering Engine for the same reason.

    also happen with transfers in and out of a VM
