What is Malware Defense?

Malware Defense is a rogue anti-spyware program that is promoted through the use of Trojans and other malware. Once installed, this program will perform a scan and then state that your computer is infected with a variety of malware. If you try to use Malware Defense to remove any of these infections it will state that you need to purchase the program first before it will attempt to do so. This is a scam, though, as the the files it states are infected are either legitimate Windows files or fake results. It is only showing you the results in order to make you think that you are infected so that you will then purchase Malware Defense. Therefore, please do not attempt to manually delete any of the files it states are infections as you may remove legitimate Windows files that could affect the proper operation of your computer.

While Malware Defense is running you will also see numerous security alerts appear on your computer. These alerts will state that your computer is infected or that it is sending your private data to the Internet. Two of the more common messages you will see state that Internet Explorer and Windows Messenger are infected with malware and prompt you to purchase Malware Defense in order to protect your computer. Like the scan results, these security warnings are all fake and are only being shown to further scare you into thinking you are infected.

Without a doubt, Malware Defense was created to scam you into thinking you have a computer problem so that you will then purchase the program. Please do not purchase this program, and if you already have, you should contact your credit card company to dispute the charges. To remove Malware Defense please use the removal guide below.

Self Help Guide

This guide is intended for advanced computer users only. Please ensure your data is backed up before proceeding. If you’re uncomfortable making changes to your computer, consider having a professional help clean your computer.
  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If this is the case, then you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive.

  3. This infection changes your Internet Explorer settings to use a proxy server that will not allow you to browse any pages on the Internet. Therefore, if you only have Internet Explorer installed, we will first need need to fix this problem so that we can download the utilities we need to remove this infection. If you already have another browser installed, then you can skip to step 4 to proceed with the removal instructions. I still advise that you do all of these steps so that Internet Explorer works as well.

    Please start Internet Explorer, and when the program is open, click on the Tools menu and then select Internet Options as shown in the image below.

    Internet Explorer Tools Menu

  4. You should now be in the Internet Options screen as shown in the image below.

    Internet Options screen

    Now click on the Connections tab as designated by the blue arrow above.

  5. You will now be at the Connections tab as shown by the image below.

    Internet Options connections tab

    Now click on the Lan Settings button as designated by the blue arrow above.

  6. You will now be at the Local Area Network (LAN) settings screen as shown by the image below.

    Proxy Settings screen

    Under the Proxy Server section, please uncheck the checkbox labeled Use a proxy server for your LAN. Then press the OK button to close this screen. Then press the OK button to close the Internet Options screen. Now that you have disabled the proxy server you will be able to browse the web again with Internet Explorer.

  7. Now we must end the processes that belong to Malware Defense so that it does not interfere with the cleaning procedure. To do this, please download RKill from the following link.

    RKill Download Link - (Download page will open in a new tab or browser window.)

    When at the download page, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.

    If you are unable to connect to the site to download rkill, please go back and do steps 3-6 again and make sure the infection has not enabled the proxy settings again. You may have to do this quite a few times before you can get the file downloaded. If you still cannot download the program on the infected computer, you should download it to a clean computer and copy it to the infected one via a USB flash drive or CDROM.

  8. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Malware Defense and other Rogue programs. Please be patient while the program looks for various malware programs and ends them. When it has finished, the black window will automatically close and you can continue with the next step. If you get a message that RKill is an infection, do not be concerned. This message is just a fake warning given by Malware Defense when it terminates programs that may potentially remove it. If you run into these infections warnings that close RKill, a trick is to leave the warning on the screen and then run RKill again. By not closing the warning, this typically will allow you to bypass the malware trying to protect itself so that RKill can terminate Malware Defense . So, please try running RKill until the malware is no longer running. You will then be able to proceed with the rest of the guide. Do not reboot your computer after running RKill as the malware programs will start again.

    If you continue having problems running RKill, you can download the other renamed versions of RKill from the RKill download page. Both of these files are renamed copies of RKill, which you can try instead. Please note that the download page will open in a new browser window or tab.

  9. At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following location and save it to your desktop:

    Malwarebytes Anti-Malware Download Link (Download page will open in a new window)

  10. Once downloaded, close all programs and Windows on your computer, including this one.

  11. Double-click on the icon on your desktop named mbam-setup.exe. This will start the installation of MBAM onto your computer.

  12. When the installation begins, keep following the prompts in order to continue with the installation process. Do not make any changes to default settings and when the program has finished installing, make sure you leave Launch Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.

  13. MBAM will now start and you will be at the main screen as shown below.

    Malwarebytes Anti-Malware

    Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.

  14. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.

    Malwarebytes Anti-Malware

  15. When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different than what is shown in the image below due to the guide being updated for newer versions of MBAM.

    MalwareBytes Scan Results

    You should now click on the Remove Selected button to remove all the seleted malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.

  16. You can now exit the MBAM program.

Your computer should now be free of the Malware Defense program. You may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future, as if you had the real-time protection component, that comes with the paid for version, activated it would not have allowed this infection to install.
