Apologies if I have missed essential elements of this thread, I have only just joined this forum. I have been using Malwarebytes (paid subscription) following a recommendation from Apple support staff and was happy with it. Just like other posts I discovered today when checking activity monitor, that RTprotection and kernel processes eat up huge `amounts of CPU time on my MacBook Air running High Sierra. From a first view of the various posts I was under the impression that Malwarebytes had fixed this issue. What do I need to do to resolve this? It makes my MacBook extremely slow.
Thanks for any suggestions
