Yo, when im on startup with nothing opened, the antimalware service usage is 0%. But when I open every game i have, it spikes - even up to 40%, causing stutters. I tried everything and its the same as it was. Even reinstalling windows didnt helped. I have an i7-13620H CPU and rtx 4060. I have also tried some logs so see what happens when I get the stutters and it creates folders in game files.

    Yes, it seems to help. I did a reboot to be sure - its luckily the same, after 2-3 minutes it optimizes CPU to a 50% usage. The 95C when opening is not the best but its cooler after few seconds so i wont be worried about it.

    So i ran another game where u need good PC to play at good settings - The Witcher 3.

    And, everything was perfect here, i think i dont even need to show a ProcMon log. 40% CPU usage and 0 stutters (tested in 2 reboots) on Ultra and Ray Tracing Max.

    So i think thats all from me, thank you very much for help - you are definitely a nice person. When i will find a new problem - i will definitely write here.

    :)

    I'm glad to hear that there has been an improvement. Now that you've added the exclusions, you may run another trace to see what Defender is scanning.

    I tested it, and it reduces Antimalware CPU usage to like max 10%, but CPU still gets to 80% due to the Omen command Center background working on 20%. I checked and there isnt any update - sadly.

    Edit 1: 1 minute after loading the game CPU gets 95°C due to all the tasks in the background. But after few minutes, it luckily gets stable to 60% of CPU (with 80°C) and 100% of GPU

    Please try excluding those 4 folders. Basically, Defender scans whatever file is accessed by each process installed on the system. It's not Defender's fault; any AV will do the same on-demand scanning. If you want to test it, try Avast or any other free AV.

    For example, Steam.exe accesses a DLL. Then Defender's on-demand scanner kicks in to check if the DLL is safe. It does it for each module accessed by any process on the system. Indirectly Steam.exe (in this example) triggers an on-demand scan.

    Alright, in an hour or two i will try to again add these folder on exclusion list.

    About OmenControlCenterBackground - its the part of OMEN Gaming Hub and when I disable it - the gaming hub just doesnt work until reboot. I didnt found any way to disable it except Task manager. BUT when I will add the exceptions - i will check if I have any updates to the software, maybe it will fix it.

    But why does the Defender scans so much that it uses over 20% of my processor??
