What you should know first: this is not an antivirus. Malwarebytes Premium suite is dedicated to detecting and preventing online threats, but not local malware. The method used by the developers is behavior analysis (instead of signature check), and it helps to do the work really fast. The full system scan is about 9-10 times faster than other apps offer.
There are also web protection modules, exploit shield, specific patches for known insecurities that only apply when the obstructed version of the software is detected. Though it’s the most intelligent suite for today, it has no ambitions of covering all the vulnerabilities as a standalone suite, so its rate of detected threats can be disappointing if you use it on its own. Instead it integrates with other anti-phishing or antivirus solutions to get the best result.
The lack of its own antivirus is recompensed by integrating with Windows Defender or other dedicated antivirus suite. These duets don’t require extra system resources and work smoothly.
Not a versatile security solution, Malwarebytes can ultimately improve the performance of any top security suite in both speed and reliability. As an extra tool it has no rivals.
