WinDefender 2009 is the successor to to rogue anti-spyware program named WinDefender 2008. WinDefender is advertised through the use of Trojans that display fake security alerts stating that your computer is infected or being attacked. These alerts then state that you should download and install WinDefender 2009 in order to protect yourself. Once WinDefender is installed, the program will be configured to start automatically when the computer starts. Once running, WinDefender 2009 will scan your computer and display a variety of malware that cannot be removed unless you first purchase the software. The funny thing is that most of the files that WinDefender finds will actually be the Trojans that installed it in the first place.
While running, WinDefender will also display pop-ups stating that your computer is infected and if you would like to purchase a program that can help you. This is just an advertisement that is currently promoting Total Secure 2009. This pop-up should be closed, and ignored, as it is just a further tactic to try and take your hard earned money.
The below guides will walk you through removing WinDefender 2009 and any associated malware that may have been installed with it.

To remove WinDefender 2009, follow these steps:
This removal guide may appear overwhelming due to the amount of the steps and numerous programs that will be used. It was only written this way to provide clear, detailed, and easy to understand instructions that anyone can use to remove this infection for free. Before using this guide, we suggest that you read it once and download all necessary tools to your desktop. After doing so, please print this page as you may need to close your browser window or reboot your computer.
To terminate any programs that may interfere with the removal process we must first download the Rkill program. Rkill will search your computer for active malware infections and attempt to terminate them so that they wont interfere with the removal process. To do this, please download RKill to your desktop from the following link.
When at the download page, click on the Download Now button labeled iExplore.exe. When you are prompted where to save it, please save it on your desktop.
Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with WinDefender 2009 and other malware. 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 a log file will open. Please review the log file and then close so you can continue with the next step. If you have problems running RKill, you can download the other renamed versions of RKill from the rkill download page. All of the 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.
Do not reboot your computer after running RKill as the malware programs will start again.
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:
Once downloaded, close all programs and Windows on your computer, including this one.
Double-click on the icon on your desktop named mb3-setup-1878.1878-220.127.116.119.exe. This will start the installation of MBAM onto your computer.
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.
MBAM will now start and you will be at the main screen as shown below.
We now need to enable rootkit scanning to detect the largest amount of malware that is possible with MalwareBytes. To do this, click on the Settings button on the left side of the screen and you will be brought to the general settings section.
Now click on the Protection tab at the top of the screen. You will now be shown the settings MalwareBytes will use when scanning your computer.
At this screen, please enable the Scan for rootkits setting by clicking on the toggle switch so it turns green.
Now that you have enabled rootkit scanning, click on the Scan button to go to the scan screen.
Make sure Threat Scan is selected and then click on the Start Scan button. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
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.
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.
You should now click on the Remove Selected button to remove all the selected 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.
You can now exit the MBAM program.
Now you should download HitmanPro from the following location and save it to your desktop:
When you visit the above page, please download the version that corresponds to the bit-type of the Windows version you are using.
Once downloaded, double-click on the file named HitmanPro.exe (for 32-bit versions of Windows) or HitmanPro_x64.exe (for 64-bit versions of Windows). When the program starts you will be presented with the start screen as shown below.
Now click on the Next button to continue with the scan process.
You will now be at the HitmanPro setup screen. If you would like to install the 30 day trial for HitmanPro, select the Yes, create a copy of HitmanPro so I can regularly scan this computer (recommended) option. Otherwise, if you just want to scan the computer this one time, please select the No, I only want to perform a one-time scan to check this computer option.
Once you have selected one of the options, please click on the Next button.
HitmanPro will now begin to scan your computer for infections. When it has finished it will display a list of all the malware that the program found as shown in the image below. Please note that the infections found may be different than what is shown in the image.
You should now click on the Next button to have HitmanPro remove the detected infections. When it is done you will be shown a Removal Results screen that shows the status of the various infections that were removed. At this screen you should click on the Next button and then if prompted you should click on the Reboot button. If HitmanPro does not prompt you to reboot, please just click on the Close button.
Once your computer has has restarted or you pressed the Close button, you should now be at your Windows desktop.
