I need an help for one my friend.

In last days, some time (very random event !) his LFS start to go slow and his fps, normal at 120-130, go to 5-7 fps.

So we decides to check his attive process, using process monitor.

And after some days we check that u can see in attach, about "killer server".

It's normal ?

Killercreation.co.uk is a server host, so you just had a normal LFS connection to a server hosted there.

Are you sure it's not Avast starting an update or scheduled scan? I think it should have the option to disable invasive scanning if a fullscreen app is active somewhere...

Maybe you could try running in windowed mode so you can easily see in the taskmanager what program is active/causing the slowdown once it happens.

But that process are "normal" ?

Looks all normal to me.
