Malwarebytes is a decent anti-malware or you could say antivirus for Windows operating systems. It can block malicious URLs, IP address, block most ransomwares and RAT/backdoors. Although no antivirus program guarantees 100% protection, but if you are working in office environment and want to keep your PC workstation safe from getting infected from email attachments and suspicious .exe files, Malwarebytes real-time protection might be your answer.

I have seen many users who cannot upgrade Malwarebytes Free and Malwarebytes Premium program on Windows 10/11 OS. Clicking ‘Check for Updates’ from taskbar icon won’t update it. Even if you try ‘Check Update’ or ‘Update Available’ button in-app on older versions, nothing happens, it gets stuck in loop and closes itself.



The broken update/upgrade feature could be due to many reason, such as: corrupted installation, malware blocking connection to servers, Windows defender interference, or an EoL (End of Life) Malwarebytes installation.
