Clear Malwarebytes Cache on Mac
To get space back, first check whether Malwarebytes offers a clearing option in its own settings. If it does not, remove only old log files and quarantine items you no longer need, and leave its settings and protection components alone.
Clear the Malwarebytes cache without guessing

Malwarebytes cache folders you can clear
Malwarebytes has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.
What the Malwarebytes cache holds and when clearing helps
Specific to Malwarebytes
The space is used by several folders. Your settings and logs sit in ~/Library/Application Support/Malwarebytes, while system-wide protection components, definitions, and quarantine are kept elsewhere on your Mac. Clearing helps when scans feel slow, when the quarantine has grown large, or when old log files have piled up. Settings, protection components, and the background services that run real-time protection are not cache and should stay where they are.
What happens after you clear the Malwarebytes cache
Removing old logs or quarantine items does not delete your settings, and deleting the app on its own does not remove these folders either. Your premium license is tied to your Malwarebytes account and can be moved to another device, so it is not lost when you clear files. Log history you delete cannot be recovered once the Trash is emptied, and quarantined items you remove are gone for good, so review them first. Real-time protection keeps running through its background services.
