Customers often ask if Malwarebytes on Mac even scanned their computer, because it's over so quickly - less than a few seconds in some cases.
Malwarebytes for Mac is not broken, though; it's really just that fast! The reason is that Malwarebytes is performing whats called a "quick scan." Rather than scanning the entire hard drive for files that are known to only be installed in specific locations, it simply looks for those things in those specific locations.
For example, when scanning for browser extensions, it only makes sense to look in specific locations, outside of which a browser extension cannot function. Safari extensions can only live in Safari's extension folder (on older systems) or inside apps in the Applications folder on newer systems. There's no need to look in any other locations. In this way, we not only keep Malwarebytes for Mac clean, lean and fast, but we also limit the possibilities for false positives.
