Step 1. If you have a printer, make sure to print out this tutorial. If you do not have a printer, save this tutorial, go out to a copy center and print it out there.

If you already know how to install a piece of software, proceed to step 4. If you do not know how to do this, we’ll walk you though it all:
- The Select Setup Language window should have popped up. By default, the language in which the software will be installed is set to English, but you can change this. The software provides support for 30+ languages. After selecting the language of your choice, click OK. It would be best to just leave it set to English though.
- The Malwarebytes’ Anti-Malware Setup Wizard will now popup. Just click Next.
- You will be presented with the License Agreement. Click I accept the agreement and then click Next. If you do not accept the agreement you will not be able to continue.
- Keep clicking Next until you get to the Ready to install window. Now click Install. After the installation process completes click Finish. Do not uncheck the boxes next to Update Malwarebytes’ Anti-Malware or Launch Malwarebytes’ Anti-Malware.
Step 4. The Malwarebytes’ Anti-Malware application will launch automatically. The Perform quick scan option should be checked by default – if it isn’t then check it and then click Scan. You are well advised to close all running apps before clicking scan. This will ensure the scan for Windows System Defender will complete swiftly.
Malwarebytes’ Anti-Malware will start scanning your files for signs of Windows System Defender. This may take a while, so be patient. It all depends on how powerful your computer is and how many files Malwarebytes’ Anti-Malware has to scan.
When the scan for Windows System Defender is complete you will be presented with a notification box. Click OK to close the notification box and go to the main Scanner screen. Click Show Results and you will be presented with a list of all the infected files Malwarebytes’ Anti-Malware has detected.
Step 5. Click Remove Selected and Malwarebytes’ Anti-Malware will remove all the infected files it has detected. It may be necessary to restart your computer in order to remove some of these files. After Malwarebytes’ Anti-Malware is done removing all the infected files, it will open Notepad and present the scan log to you. You can review the log at your leisure – save it If you want.
