However, some people experience a hard time for using it. No matter what they do, they could not figure out a way to open it. There could be a number of reasons for that happening. It also makes user wonder whether Malwarebytes is safe?

In this guide, we would discuss the possible reasons why Malwarebytes won’t open and some ways to fix it.

Why is Malwarebytes not Opening in Windows?

After giving several tries, you might be wondering why won’t Malwarebytes open on your system? Well, there can be two main possible reasons for that.

1. Malware Attack

The first reason could be that malware has attacked your device and is preventing the executable file for launching the Malwarebytes to run. The executable file mbam.exe is responsible for running the Malwarebytes. It is either been blocked or deleted by the malware which is already present on your system. The only solution is to rename the executable file. We will discuss how to do that in the next section.

2. User Account Corrupted

If you are running Windows 10 with a corrupted or damaged user account, then it will block several applications to run, including Malwarebytes. Operating Windows 10 without a proper user account can be harmful to your system as well as your personal data too. In such cases, you need to try switching to a different profile. 

Fix the Malwarebytes not opening issue

Method 1: Rename the Executable File

If the problem is due to the executable file, try to rename it. As already mentioned that some advanced malware blocks the executable files of anti-malware programs so that it cannot interfere in their malicious activity.

Renaming the Malwarebytes’ executable file is straightforward.

1. Right-click on the Malfarefox shortcut icon present at the desktop, and from the context menu, click on Open File Location option to find the installation folder of the application.

2. In the installation folder, look for the executable file named mbam.exe.

5. After renaming, relaunch Malwarebytes and check if it opens. Click on the scan option upon its opening, and Malwarebytes will then update its database.

6. Restart your computer after the scanning is completed. Again open the Malwarebytes application and recheck if it is running or not.

1. Go to settings from the Start menu and look for Accounts and click on it.
