    I’m running CLS2SIM on a VM, because McAfee on the host PC (also running X-Plane) reports it as malware.
    It reports:

    Adaptive Threat Protection repaired C:\Program Files (x86)\Brunner Elektronik AG\CLS2Sim\CLS2Sim.exe file, because its reputation (Known Malicious) is below the configured Clean threshold.
    I have logged this with Brunner support, but they blame McAfee!

    As a work-around I’m instead running a Windows 10 VM under VirtualBox, and passing the USB device through to that.
    Windows defender on the VM also complained about CLS2SIM, but I was able to over-ride it.

    HOWEVER… the VM regularly crashes when running CLS2SIM.
    Windows Event viewer shows this event:
    The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x0000000000000028, 0x0000000000000002, 0x0000000000000001, 0xfffff8037a01307c). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 9d6bf167-b1e3-4bdb-bc6b-438f5ccc2cbb.

    I have also tried another VM, running Windows 10 Enterprize, from here:

    Exactly the same, runs perfectly, but after starting CLS2SIM, it crashes within 20-30 minutes.

    Any suggestions how to resolve this?


    Easiest suggestion is to create an exclusion for CLS2SIM in McAfee.

    Best solution is to stop using McAfee as it’s useless anyway. Their method of protection is to presume everything is malicious and block it. I recommend ESET for anti virus protection it’s much more intelligent and pretty much set and forget if you want to use it that way.


    Unfortunately, I can’t. The PC is provided by my employer, and they enforce the AV, which I cannot change or disable.
