Hi,
I have researched the etl log which you send to Onedrive. I find there are many process related to browser that read low or very low.
Based on my research, ntoskrnl.exe
is responsible for various system services such as hardware virtualization, process and memory management, thus making it a fundamental part of the system. It contains the cache manager, the executive, the kernel, the
security reference monitor, the memory manager, and the scheduler. Therefore, the process itself is not virus, but we cannot exclude the reason that the virus infect the process.
I suggest you use SFC to repair the system files to troubleshoot the issue.
Due to I noticed the process related to browser, you would better disable all the add-ons in browser.
Wish you will troubleshoot the issue smoothly.
Best Regards
Simon
