What is Windows Security System?

Windows Security System is a rogue anti-spyware program from the Rogue.Contra family. This rogue displays fake scan results and warnings in order to scare you into thinking your computer is infected. This program is installed via two methods. The first method is Trojans that download and install the program on to your computer without your permission. The second are fake online scanners that state your computer is infected and then prompt you to download and install the program.

When installed, the rogue will also create numerous harmless files in your Windows Temp folder that will then be detected as malware when Windows Security System attempts to scan your computer. If you attempt to use the program to remove any of the files it detects as infections, it will state that you need to purchase the program before you can do so. As all of the files it detects as infections are harmless or legitimate Windows files, please disregard the scan results and do not purchase the program.

  • Scanning screen
  • Fake Alert
  • Fake loss of data alert

While running, Windows Security System will also display fake security alerts on your computer. These alerts are designed to make you think that you have a severe computer infection or that your computer is sending private data to a remote location. The text of these alerts include:

Warning! System Under Attack
Threat detected: Worm

Possible loss of data!
Your online guard helps to stop unauthorized changes to your computer.
Details: Too many privacy violation attempts on your computer!
The details about your credit card, post address, phone numbers from the submitted forms can be lost.

As you can see, this program was developed to scare you into thinking that your computer has a serious computer security problem so that you will then purchase it. Therefore, do not purchase Windows Security System for any reason, and if you already have, please contact your credit card company and state that the program is a computer virus and a scam and that you would like to dispute the charge. To remove this infection and related malware, please follow the steps in the 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 or ask 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 Windows Security System 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 Windows Security System 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 Windows Security System 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 Windows Security System . 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 mbam-setup.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.

  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 Windows Security System 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.
