Announcing Malwarebytes 4.0: smarter, faster, and lighter

Malwarebytes was founded on the belief that everyone has a fundamental right to a malware-free existence. Every product we make is built on that premise. That’s why we’ve been hard at work on the latest version of Malwarebytes for Windows that not only sports a whole new look, but packs cutting-edge detection methods into a lightweight, lightning-fast program.

We proudly present: Malwarebytes 4.0.

Malwarebytes 4.0 signifies a big step forward in the fight against online crime. It uses smarter technologies to quickly identify stealthy malware and scan faster than ever—all with 50 percent less impact on CPU during scans.

Malwarebytes 4.0: What’s improved

Our first step in taking malware defense to the next level was making important improvements to our existing Malwarebytes for Windows technologies. They include:

  • Improved zero-hour detection that pinpoints new threats as they arise
  • Upgraded behavioral detection capabilities that catch more diverse threats—even those that use signature evasion
  • Improved overall performance and scan speed
  • Redesigned User Interface (UI) for easier, more intuitive functionality
  • Simplified Windows Security Center integration settings
  • Enhanced web protection technology

Malwarebytes 4.0: What’s new

Malwarebytes 4.0 introduces Katana, our brand-new detection engine that uses patented, dynamic methods to recognize zero-hour, often polymorphic malware even before it’s released in the wild. These same methods have been optimized with a faster threat definition process, so they’re not only smarter and more accurate, but using them results in faster scans while taking up less CPU.

“Polymorphic threats have changed the game in cybersecurity. By the time traditional antivirus creates a signature for these threats, it can be too late. Cybersecurity providers need to stay ahead of the game by recognizing potential threats before they can cause damage,” said Akshay Bhargava, Chief Product Officer at Malwarebytes.

“Malwarebytes 4.0 is designed to block these evolving threats in record time using innovative detection technology. Our new intuitive user interface helps customers more easily engage with their cybersecurity. Furthermore, the new engine is optimized and requires 50 percent less of the CPU while scanning.”

A new look and more integrations

The redesigned UI of Malwarebytes 4.0 is more informative, intuitive, and simple to navigate. Increased automation means users receive the latest updates to the product with less effort on their part. A threat statistics dashboard allows users to see which threats are blocked by Malwarebytes in real time—both on their own device and on machines throughout the world. The new UI also features dynamic integration with the Malwarebytes Labs blog, keeping customers informed on the latest cyberthreats, trends, and protection advice.

In addition, threats blocked or quarantined by Malwarebytes 4.0 are now linked directly to our Threat Center, so you can read up on each threat’s profile, including symptoms of infection, attack methods, and ways to remediate or protect against it.
