Security Defender and Defender Pro 2015 Removal Guide

  • March 25, 2015

Security Defender, or Defender Pro 2015 as it's shown on the program's web site, is a rogue anti-spyware program that displays fake security alerts, false scan results, and blocks you from running your legitimate programs. This program may look familiar as it tries to impersonate Microsoft Security Essentials by using the same graphical user interface. This scareware is distributed through web sites that have been hacked to run exploit kits that try to install the program by exploiting vulnerabilities on your computer. It is also distributed by Trojans that pretend to be programs required to view an online video, but instead install the infection. These types of Trojans are typically encountered on adult web sites.

  • Fake Security Alert
  • Fake Security Alert

When installed, Security Defender will run from your Documents folder and then configure a Windows registry key to start the program every time you login to Windows. Once started it will pretend to perform a scan of your computer that will state you have numerous infections present. If you try to use the program to remove these threats, though, it will prompt you to first purchase the program. As the scan results are fake, please ignore them.

Security Defender also attempts to protect itself from being removed by terminating any program that you try to run. When it terminates a program it will then state that the file is infected with different types of infections such as Win32/Wadnock. The text of this message is:

Review harmful or potentially unwanted software

Your computer might be infected with: Win32/Wadnock.
Windows has detected potential threat that might compromise your privacy or damage your computer. This trojan is dangerous and executes commands from an attacker.

Your access to this program may be suspended until you take an action.

As this alert is false and only designed to scare you, please ignore it.

While the infection is running it will also display a variety of alerts and sounds that are meant to scare you into thinking your computer has a problem. Some of these scare tactics are truly bizarre such as displaying a strange noise and then making your screen appear distorted. Some of the text alerts you may see include:

Virus detection alert.
System has detected security setting changes due to malware. This threat is dangerous, exploits the computer, and provides access to user files. A scan required to complete remediation.

System attack detected.
Unknown program tries to collect a personal info, compromise your privacy, or damage your PC.

Details:
Attack from: 249.251.51.131 port: 18280
Attack port: 37825
Threat: Password.WIn32.OnlineGameSxa

Just like the scan results, these security alerts, noises, and screen distortions are all meant to scare you into purchasing the program and should be ignored. Finally, Security Defender will hijack your web browser so that you cannot browse the web. When you attempt to do so, you will be shown a page that states that the site you are visiting may be a security risk.

As you can see, this infection was created to scare you into thinking your computer has a security problem so that you would purchase the program. It goes without saying that you should not purchase it, and if you already have, please contact your credit card company and dispute the charges. To remove Security Defender, Defender Pro 2015, and related malware please use the guide below.

 

Self Help Guide

This guide contains advanced information, but has been written in such a way so that anyone can follow it. Please ensure your data is backed up before proceeding.

If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
  1. Print out these instructions as we may need to close every window that is open later in the fix.

  2. Reboot your computer into Safe Mode with Networking. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard. Eventually you will be brought to a menu similar to the one below:


    MalwareBytes Anti-Malware Screen

    Using the arrow keys on your keyboard, select Safe Mode with Networking and press Enter on your keyboard. If you are having trouble entering safe mode, then please use the following tutorial: How to start Windows in Safe Mode

    Windows will now boot into safe mode with networking and prompt you to login as a user. Please login as the same user you were previously logged in with in the normal Windows mode. Then proceed with the rest of the steps.

  3. 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.

  4. Before we can do anything we must first end the processes that belong to Security Defender so that it does not interfere with the cleaning procedure. To do this, please download RKill to your desktop 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.

  5. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with Security Defender 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 Security Defender 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 Security Defender . 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.

  6. 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)

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

  8. Double-click on the icon on your desktop named mb3-setup-1878.1878-3.0.6.1469.exe. This will start the installation of MBAM onto your computer.

  9. 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.

  10. 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.

  11. 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


  12. 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.

  13. You can now exit the MBAM program. If Malwarebytes did not prompt you to reboot your computer, please do so that you are back in normal mode.

  14. As many rogues and other malware are installed through vulnerabilities found in out-dated and insecure programs, it is strongly suggested that you use Secunia PSI to scan for vulnerable programs on your computer. A tutorial on how to use Secunia PSI to scan for vulnerable programs can be found here:

    How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector

 

Your computer should now be free of the Defender Pro 2015 program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
