Malwarebytes Anti-Malware 4.5.21 (offline installer)


Malwarebytes is a high performance anti-malware application that thoroughly removes even the most advanced malware and spyware. Malwarebytes version 4.xx brings comprehensive protection against today’s threat landscape so that you can finally replace your traditional antivirus.

You can finally replace your traditional antivirus, thanks to a innovative and layered approach to prevent malware infections using a healthy combination of proactive and signature-less technologies. While signatures are still effective against threats like potentially unwanted programs, the majority of malware detection events already come from signature-less technologies like Malwarebytes Anti-Exploit and Malwarebytes Anti-Ransomware; that trend will only continue to grow. For many of you, this is something you already know, since over 50% of the users already run Malwarebytes as their sole security software, without any third-party antivirus.

What’s new in v4.5.21.231:

  • Smart Scan - We just changed the game for scheduled scans with Smart Scan! The Smart Scan option now allows a scheduled scan to start only if the computer is in an idle state. Limiting scheduled scans to start only during idle time will provide a significant performance improvement as the default nightly scheduled scan (that is typically skipped because the device is usually powered off at night) will no longer kickoff when the computer is first started and hog resources that are needed for the task at hand. Smart Scan is on by default for all new scheduled scans.
  • Scan reminder for new downloads - Our Free product is now even more amazing with new logic that reminds you to scan when we find new files in the download folder. While this isn’t a substitute for Real-Time Protection, it helps build better security habits.
  • New background - Malwarebytes has a fresh new look thank to the newly added Clean Sky background. Now users can choose between three great backgrounds to personalize Malwarebytes.
  • Improved error handling for update issues
  • Minor performance improvements
  • Added translations for new UI flows
