The major advance here is the addition of real-time protection from malware, meaning that Malwarebytes Premium keeps watch over your device at all times, shielding it from anything malicious. Malwarebytes Premium adds a number of features into the mix over and above the basic malware hunting capability that you get with the free edition. There's a lot more going on behind the scenes that makes this much more complex than I've just laid out, but as someone who doesn't work on that part of our product, that's the best explanation I can provide.(Image credit: Malwarebytes) Malwarebytes Premium: what features does it have? This is the list of signatures we have of known bad files that we can easily clean up and remove.

If it gets blocked by exploit protection, then it can't infect you and it will be removed. This could be something that found an exploit in Word, Adobe Reader, etc.

However, as you mentioned, this generally requires us to update the database of known bad websites so can sometimes be a bit slow and maybe the file does get downloaded. In this situation, our Web Protection is very good at blocking malicious websites. You generally have to download the virus from somewhere.To explain a bit more, here's a typical flow:

If we can stop the infection from getting to the computer in the first place, then the rootkit can't get to a point where it can bypass detection. While rootkits are designed to bypass a lot of AV, this is why we rely on our multi-layer protection. We are continuously improving the logic though. We've had machine learning and heuristic for a year now, if not longer.
