Glad you are running good again. It might not be a bad idea to reboot, then update Malwarebytes again and then do another scan. I've had fleas before that were not detected on the first scan but showed up after doing multiple scans.
If you aren't getting those annoying pop ups telling you to buy their Spyware program chances are you cleaned it all but better to be safe than sorry!!
And yes, you should always have your AV program running.
"Sort of" is such a harmless thing to say. "Sort of". It's just a filler. "Sort of" - It doesn't really mean anything. But after certain things, "sort of" means everything. Like after "I love you" or "You're going to live" or "It's a boy".
