    I don't know which version you used of McAfee and when the last time was that McAfee was updated, but if you want to use McAfee again you could but with an updated version.
    A bluescreen with an AV program is usually due to the problem that it wasn't updated for a long time or there is a bug.

    I understand that the drivers of McAfee and Juniper are causing problems, but if i remove my McAfee, dont i need to get another antivirus software? Also i need juniper to access my university's network. Did the command you suggested fix the problems with the drivers already?

    If you remove McAfee correctly, you'll be able to enable the built-in antivirus Windows Defender.
    When you install another antivirus Windows Defender will be disabled automatically.

    The commands I suggested are not doing anything with these drivers.
    They only check the system files and repair them if they find problems.

    Update juniper if possible is the only thing I can recommend outside of removing it.

    hey uhm sorry for opening up this thread again, but the frequency of blue screens have been increasing as of late, and i have even removed mcafee and activated windows defender already. do you mind helping me take a look again to see if any new problems have arisen?

    I have checked the latest 3 and they are all blaming the Juniper driver

    At first sight is the driver of your network card being blamed, but digging a little deeper shows NETIO (Network In/Output system) meaning a 3rd party driver is trying to access the internet.

    Please update the software or remove it.

    Code:
    0: kd> lmvm jnprnsstart             end                 module name
    fffff800`e3532000 fffff800`e35b8000   jnprns   T (no symbols)
