    BSOD - Bad Pool Caller/Header


    Hi, I have the Bad Pool Caller BSOD when I turn on my web browser or at other random moments. This happens ONLY when I have wifi ON. With wifi off the computer works fine. Recently I installed Comodo Internet Security but it didnt show up in installed programs so I used the uninstall app delivered with it. Later I installed Kaspersky. Then the problems begun. I cant use internet but the Metro Mail app works (others like News dont connect to the net).
    I checked this thread:
    bad_pool_caller
    I cant open my minidump file so Im posting it here.
    I dont have any programs listed in this topic.
    Please help me solve this problem.

    Welcome to EightForums.

    The BSOD seems to be caused by Kaspersky KNEPS Power driver I would uninstall Kaspersky and use the default antivirus app on Win 8 and see if it stops the BSOD problem.

    BAD_POOL_CALLER (c2)
    The current thread is making a bad pool request.  Typically this is at a bad IRQL level or double freeing the same allocation, etc.
    Arguments:
    Arg1: 0000000000000007, Attempt to free pool which was already freed
    Arg2: 00000000000011c1, (reserved)
    Arg3: 00000000040d000e, Memory contents of the pool block
    Arg4: fffffa8005fb1a00, Address of the block of pool being deallocated
    
    Debugging Details:

    Hope this helps.

    Thank you for the response. This solved the BSOD problem but I still cant access the internet. Chrome suggests to change the proxy settings. I did it but it doesnt work. Only one program uses the internet: Mail app, others, including other Metro programs like news cant access internet.

    Have you tried updating your network drivers? Are there any available for your Win 8 System?

    Its funny, cause I opened Windows Update and it recommended 1 optional update - Zune software. It is downloading at the moment. Should I look for network drivers on windows update or manually in the internet?

    That's weird.

    If windows update offers the drivers no need to look for them on the internet.

    I always had my drivers and other things available on Win Update up-to-date. Now it doesnt offer any drivers (zune is a totally different software). Its strange that there is an internet connection (windows update and mail app work) but other applications dont see it.

    Perform a clean boot:

    Perform a System File Check:


    Restart the system and see if that makes any changes?

    I performed a clean boot but it did nothing. The diskcheck found 1 error and repaired it. The internet still doesnt work. Any new ideas?
