Ira, I am slowed down, otherwise, I'm not opening Activity Monitor.

Usually, most time, internet is slow, so checking what is slowing it down. REcently clone app Super Duper was going real slow, so then

I did find Malware Bytes was culprit (though that was coded very obtusely).

What JOe is saying is very intriguing, I don't get it fully, but get the gist.

That said Activity Monitor is far from easy to deal with as so many culprits are coded not to take blame. .. that 's by guess on that so far..
