Malware app

Thanks for answering my first question. Now I have additional questions. I had several PUPs which apparently came from what I thought was an innocent upgrade to a browser support app. The apps looked suspicious and I couldn't seem to get rid of them and my whole system slowed down where it was taking up to a minute to just open a web page on any one of my browsers. Someone on the forum suggested Malwarebytes, which I downloaded and ran, which seems to have restored my system and I got rid of the PUPs. The app "Reports" indicate: 2 threats quarantined, 3 detected and remediated. Then under "manual scan" it shows 24 "Threats" detected, 23 remediated. Then under "Real-time" scan it shows 1 threat, 1 remediated.

My new questions now are:

1. My Malwarebytes "settings" show default action "Quarantine" What does that mean? I thought I got rid of them.

2. I'm set by default to check for PUPs every hour. Is this what I should have? If not, why?

3. Info on this app indicates I have a "Trial" version, but says it "...will be downgraded from Premium to Free in 13 days." What does that mean?

4. A box shows "Activate License." What does that mean and should I click it and why?

5.The "Upgrade Now" box indicates a cost to me of $60 for personal use, $120 for office per year. Who would I be paying this to? Is this the Apple iTunes Store? If not, I want to know who I'm dealing with. It's not like I can pay in cash and I don't want to give out my credit card to an unknown business.
