phymem64.sys is a blacklisted vulnerable driver and is rightly blocked from loading. Removing its autorun entry should fix the issue.

Download Autoruns:

https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns 

  • Unzip and run Autoruns64.exe.
  • Accept the license agreement.
  • Once the scan completes, in the Quick Filter enter phymem64.sys
  • Right click any entry referencing the driver and delete.

You could also use Driver Store Explorer to delete the driver.

    Hi karlloeffler! Thanks for staying in touch, responding to my questions, and for the additional information you've shared with me.

    Regarding your question, it is a bit difficult to determine if it is part of a critical driver or part of a specific application file that links to the drivers.

    From what I have been able to identify regarding "phymem64.sys," it seems to be related to the developer "Shenzhen Moyea Software," which in turn is related to an online video download application. Could you confirm with me if you have any software of this category or one named "Moyea All-In-One Downloader" installed?

    Additionally, I would like us to check the drivers section, please check the following points:

    1. Go to "C:\Windows\System32\drivers" and check if "phymem64.sys" appears there. If it does, right-click > properties > details and share with me the information from these details.
    2. Open CMD as an administrator and run the following command:

    sc query phymem64

    If this file is registered as a driver, it will say so; otherwise, the system will report that the service is not installed.

    If the file is registered, run the following command:

    sc config phymem64 start= disabled

    This should help disable it so that it no longer causes an error when starting the system.

    Let me know if the shared information has been helpful. Regards.
