Malwarebytes believes that its product is ready for the responsibility thanks to the integration of the new Katana engine in the new program version. The very first thing that Windows users who install the new Malwarebytes 4.0 may notice is not the new interface but that the product registers itself as the system's main antivirus solution in the Windows Defender Security Center. The company's browser extension, Malwarebytes Browser Guard, exited Beta recently as well.

Other issues include that Controlled Folder Access blocks certain advanced installer options on Windows machines and GUI issues with high DPI and certain screen resolutions. Users who run Windows Firewall Control (which Malwarebytes acquired some time ago) will notice that Malwarebytes Self-Protection module will prevent the firewall tool from opening. The company recommends that users stay on Malwarebytes 3.x as it will continue to be supported. Note: Malwarebytes 4.0 is not compatible anymore with pre-Windows 7 operating systems.

The default installer requires an active Internet connection users who need an offline installer can download it by following the link in the second post on this page. The new version can be downloaded from the official Malwarebytes website.

Premium users, including those with lifetime keys, may upgrade to the new version for free. Malwarebytes 4.0 is offered as a Free and Premium version just like previous versions.
