The "30% CPU at idle because of System + Interrupts" issue

Welcome to the forum
thank you

It's been a while but there were some people on the forum complaining about Kaspersky being a drain/drag on the system. You wouldn't be alone.

after removing kaspersky - its so nice to work in quiet. i totally understand that this is not a solution, but maybe it will help to get roots of problem
