    Ladies and gentlemen,

    I've had this problem (minor annoyance, really) for over a year now, ever since I got this laptop. It's an Asus Zenbook, so pretty good specs, SSD drive, 8MB RAM, GPU, etc... Windows 8.1, it runs fine. But as soon as I get up, fan starts whirring like crazy, CPU usage spikes up to 50% or so. The offending processes take turns: "Antimalware Service Executable", "Host Process for Windows Tasks", "WMI Provider Host", or sometimes just "System". I went through great pains to look through the Task Scheduler and try to disable the automatic Virus Scan (Windows Defender) in as many ways as I could, but apparently to no avail. As soon as I move the mouse, computer shuts up. Some people online had issues with Conduit Search but I don't have that installed.

    It's not a real issue, but the fan blaring up every time I get up for a snack has gotten really annoying and I want to figure this out and stop it, hopefully with your help. Anything I can try, or any additional info I can provide, please let me know.

    Much appreciated!
    -Marco

    Mate,
    I have been away for a while.
    I would suggest as a starting point:
    BIOS update
    Windows update.
