Hello stilli and welcome to Seven Forums.
I've been using that exact combination since MSE was first released and it's worked well for me. Some here would say the same thing. Others would say that MSE is too basic, doesn't update often enough, scans too slow, misses too many things, etc. Ask 100 people what's best and you might get 100 different responses.
If you use common sense when surfing, know what sites you're visiting, don't click on unexpected email attachments, I think it will serve you well. I also use the free Malwarebytes for on-demand scans just in case MSE misses something (which it hasn't.)
