We have a new patch upgrade for Malwarebytes for Windows—v. 3.4.5.
We’ve started rolling out upgrades for this version via in-app upgrades. If you don't want to wait to be notified by the program that your upgrade is available you can always grab the upgrade manually by clicking Install Application Updates in Settings > Application (if you're running MB 3.2 or later). The updated installer is also available for download now from the main Malwarebytes website.
