Remove SecureDefense (Uninstall Guide)

  • October 8, 2010

SecureDefense is a rogue anti-spyware from the Wini family of fake security programs. This programs is distributed through malware that pretends to be a video codec or via fake online anti-malware scanners that state your computer is infected. When the program is installed it will be configured to start automatically when Windows starts. While installing , SecureDefense will also create hundreds of fake and harmless malware files. These fake malware files are then detected as infections when SecureDefense scans your computer. The program will not remove them, though, until you purchase it. This is a scam as the files it detects are the files it created on your computer in the first place. Therefore do not be concerned by any of its scan results.

  • Scanning screen
  • Scan results
  • Fake Windows Security Center

When SecureDefense is running it will also display a fake Windows Security Center window. This window will look exactly like the legitimate Windows Security Center, except that it suggests that you purchase SecureDefense to protect your computer. While SecureDefense is running it will also display fake security warnings and alerts that are designed to make you think that your computer has a serious computer problem or is under attack from a remote program. The text of these messages are:

Security Center Alert!
Infiltration Alert!
Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan-dropper or similar.
Do you want SecureDefense to block this attack?

Spyware Alert!
Your computer is infected with spyware. It could damage your critical files or expose your private data on the Internet. Click here to register your copy of SecureDefense and remove spyware threats from your PC.

Just like the fake scan results, these security alerts are all fake and should be ignored.

When infected with SecureDefense, Internet Explorer will become hijacked so that it displays warning messages when you browse the web. These messages are designed to make you think that the web sites you are visiting are insecure and that purchasing SecureDefense will protect your computer from being infected. The warning message that you will see is:

Reported Insecure Browsing: Navigation blocked
Insecure Internet activity. Thread of virus attack

Due to insecure Internet browsing your PC can easily get infected with viruses, worms and trojans without your knowledge, and that can lead to system slowdown, freezes, and crashes. Also insecure Internet activity can result in revealing your personal information. To get full advanced real-time protection for PC and Internet activity, register SecureDefense. We recommend you to protect your PC now continue safe Internet Browsing.

This is just another scare tactic being used by the program and can be ignored.

As you can see, SecureDefense was designed to scare you into purchasing it by display fake scan results, fake security alerts, and browser hijackings. It goes without saying that you should definitely not purchase SecureDefense, and if you already have, please contact your credit card company and state that the program is a computer infection and a scam and that you would like to dispute the charge. To remove this infection and any related malware, please follow the steps in 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. 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. Before we can do anything we must first end the processes that belong to SecureDefense 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.

  4. Once it is downloaded, double-click on the iExplore.exe icon in order to automatically attempt to stop any processes associated with SecureDefense 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 SecureDefense 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 SecureDefense . 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. If you continue having 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.

  5. 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)

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

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

  8. 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.

  9. 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.

  10. 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

  11. 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.

  12. You can now exit the MBAM program.

  13. 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 SecureDefense 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.
