    BSOD System Service Exception Netio.sys


    Over the past week I have gotten two BSOD with them both saying something about System Service Exception Netio.sys and I was just looking to find out what is going on with my PC! I have attached the minidump folder but it has 9 dumps in it but only the most recent two are relevant (060115-51734-01.dmp and 052315-38296-01.dmp). Any help would be appreciated!

    Hi FabFabian & Welcome to the forums ^_^,

    I have analysed your latest dump files and have provided an analysis for informative purposes :-


    SYSTEM_SERVICE_EXCEPTION (3b)
    An exception happened while executing a system service routine.
    Hmmm... Pretty simple, an error occurred which caused the system to crash. Let's see the stack and see if we can find anything -

    Code:
    1: kd> knL
     # Child-SP          RetAddr           Call Site

    0f ffffd001`d820b6b8 ffffe000`37ca1cc0 0xffffe000`3b8f58c0

    11 ffffd001`d820b6c8 ffffe000`36e63990 0xffffe000`38bd8ac0
    12 ffffd001`d820b6d0 00000000`00000000 0xffffe000`36e63990
    We see that the AVG Antivirus Driver told the Kernel Mode IPsec driver to copy the data of the stream to the buffer which asked the Networking Driver of Windows (NETIO.sys) to do the same. But, this resulted in a page fault which ultimately caused the system to crash. Let's see what happened -
    Code:
    12 ffffd001`d820b6d0 00000000`00000000 0xffffe000`36e63990
    1: kd> .cxr 0xffffd001d820abe0;r

    r14=0000000000000000 r15=0000000000003fd0

    NETIO!FwppCopyStreamDataToBuffer+0xa8:
    fffff800`a604ceec 488b3f          mov     rdi,qword ptr [rdi] ds:002b:00000000`00000000=????????????????
    We see that a MOVe instruction was executed which was to move the value 0 which is contained in the register RDI to the register RDI. That seems strange, doesn't it? Seems like the AVG Driver passed on some bad addresses.



    Kindly remove AVG using this **TOOL** and enable Windows Defender. Once you have uninstalled AVG, monitor the system for crashes.


    Let me know how it goes ^_^

    Thanks for the really quick reply! After the Blue Screen today I actually did uninstall AVG because of some high disk usage problems so that step is already complete. I'll monitor it for a while and tell you how it goes. Thanks again for the quick response!
