Hi Ronald,
I have used it once, but I can tell you what you need to do from the support perspective.
This issue is most proably caused by the f-secure filter driver. AV filter drivers are know to cause such issues, that is the reason why Microsoft released this article:
How to temporarily deactivate the kernel mode filter driver in Windows
https://learn.microsoft.com/en-us/troubleshoot/windows-server/performance/deactivate-kernel-mode-filter-driver
When you are troubleshooting any one of these issues, frequently, you have to do more than just stop or disable the services that are associated with the software. Even if you disable the software component, the filter driver is still loaded when you restart the computer. You may be forced to remove a software component to find the cause of an issue.
So my advice would be to contact F-Secure and ask about an update or a fix.
I hope I could help you out with that!
Best Regards,
Stoyan
