    Random BSODs "Bad_Pool_Caller"

    Over the past week or so I've been getting random BSODs with the error "Bad_Pool_Caller" out of the blue with no warning at all . Usually only happens 1-2 times a day after using my PC for a while (20-40 minutes), If I restart it after the crash it's usually fine for the rest of the day unless I restart it again in which case it usually crashes to the same BSOD again.

    There is no specific usage circumstance in which the BSOD occurs, I can be idle or playing hardware intensive games and it will happen randomly.

    DM Log file is attached.

    Thanks in advance to those that can help.

    There is a single BSOD crash dump in the uploaded zip; and that is apparently a Malwarebytes caused internet blockage BSOD.

    Based on it, I would suggest you to uninstall Malwarebytes and install a fresh downloaded copy of it.

    See how it goes. Let us know.

    This is a known problem with Malwarebytes & Bitdefender: a driver conflict between MBAM & Bitdefender.
    I'm not sure if a fresh copy would help resolve the problem given that it doesn't work for many with similar cases.

    This BSOD happens anywhere, irrespective of BitDefender. It takes place even when the antivirus is MSE in case of Windows 7. The most common cause is an expired trial or a cracked installation. Some examples:

    We are on our way of troubleshooting. If the uninstallation and reinstallation does not work, we will take the next step.

    I, in general, know what I am doing and what I am suggesting. If I feel that I am unable to control the issue, I will definitely ask for help.

    Sorry for the interruption, I didn't meant to do it, but I only wanted to let the OP know about it as the calls in the stack are similar to the BSODs I've had & seen.
    I'll leave it to you for the rest.

    My bitdefender is only a 30 day free trial with 9 days renaming. (Buying a key when it expires)
    No cracked anti-virus program is on my PC.

    I'm currently in the process of re-installing Mbam and I'll update this soon with another DM log if I encounter a BSOD just encase. (I did a disk cleanup recently so some of the dumps may have not existed in that previous log)

    When the BitDefender expires, uninstall it and activate windows defender.

    Looks like there may not be a reason for uninstalling BitDefender.
    After re-installed Mbam and re-adding an exception for Mbam in BD I've not experienced any BSOD at all recently

    I'll mark this thread as solved before I go to bed today if it remains the same way.

    I would suggest you give it a few more days. Wait at least two/three days before deciding that the issue is solved.

    Gah! Went 5 days without problem then it returned.
    Logged on and got a random "Bad_Pool_Caller" BSOD when using google chrome.
    I changed my page file's maximum limit yesterday and restarted to make sure it was in effect, I experienced no problems that day. I just changed my page file back to normal system managed on both C: and G: encase it was the problem.
