How to Fix Malwarebytes Not Updating on Windows 10

Is Malwarebytes not updating on Windows 10?

Malwarebytes, as the name gives off, is a computer protection program similar to antivirus software. The utility protects your PC from external threats, malware, viruses, PuPs, adware, etc., by performing regular database updates and scheduled scans. However, the app needs to be updated every now and then for it to work properly.

Although Malwarebytes is available in both free and premium versions, users are having trouble updating the program. The common reasons behind this problem include corrupted installation of the app, outdated Windows OS, disabled Automatic Updates feature, interference with other antivirus programs, and so on.

Before you go ahead and look for the program’s alternatives, we recommend you run a few checks to troubleshoot the issue yourself. To assist you in the process, we’ve concluded this step-by-step guide covering the most effective solutions for Malwarebytes not updating on Windows 10 error.

So what’s the wait for? Let’s get started right away!

1. Disable Windows Defender.

Before you go ahead with some troubleshooting steps for Malwarebytes not updating on Windows 10, know that you cannot run two or more softwares serving the same purpose. If you want to use Malwarebytes as your antivirus program, it’s important that you keep all other similar programs disabled.

Even if you didn’t install another antivirus other than Malwarebytes, you might have the default program called Windows Defender enabled, which may be interfering.

To disable it, follow the steps below:

  1. Head over to the Start menu and click on the search bar. 
  2. Type in ‘Windows Security’ and choose the same from the search results. 
  3. Now, select Virus and threat protection.
