f-secure slowing down my pc i will explain why

I got an email reply from f-secure today and changed the settings they told me to it does seem to run at least a bit better. but i cant really tell yet because only just changed the settings.

I will be replacing f-secure with antivir soon anyway but i might as well make f-secure run fast while i use it.
because why slow my system down with f-secure when i can get the same or better protection level from antivir on max settings with no system slow down.
