Proof Defender 2009 is a rogue anti-spyware program from the same family as Perfect Defender 2009. This rogue is promoted through the use of malware and web pop-ups that state your computer is infected and then suggest that you use an online anti-malware scanner to check your computer. When you click on this pop-up you will automatically be brought to a page that shows an advertisement that pretends to be an online anti-malware scanner. When this advertisement is finished, it will state that your computer is infected and then prompt you to download and install Proof Defender 2009. It should be noted that this advertisement has no way of knowing what is running on your computer and is just trying to trick you into thinking there is a security problem.

Automated Removal Instructions for Proof Defender 2009 using Malwarebytes Anti-Malware:


  1. Print out these instructions as we will need to close every window that is open later in the fix.

  2. Download Malwarebytes Anti-Malware, or MBAM, from the following location and save it to your desktop:

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

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

  5. 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 both the Update Malwarebytes Anti-Malware and Launch Malwarebytes Anti-Malware checked. Then click on the Finish button.

  6. MBAM will now automatically start and you will see a message stating that you should update the program before performing a scan. As MBAM will automatically update itself after the install, you can press the OK button to close that box and you will now be at the main program as shown below.

    You should now click on the Remove Selected button to remove all the listed 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.

  12. When MBAM has finished removing the malware, it will open the scan log and display it in Notepad. Review the log as desired, and then close the Notepad window.

  13. You can now exit the MBAM program.

Your computer should now be free of the Proof Defender 2009 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.
