Remove "Security Tool" a.k.a. SecurityTool Malware, Finally! (Uninstall Guide)

Finally I found the solution for the original "Security Tool" problem, and it is FREE! Read on!


So by the end of the day I was able to remove all traces of StopZilla. It took me hours, but it will take you only minutes if you heed my directions here.

I was able to finally download McAfee virus scan and start the full scan which however found nothing.

I made the full circle and the "Security Tool" nagware is popping up again. This time I looked at exactly how much money they wanted (they would not reveal what website I was connecting to to pay, everything was done on their screen, not in the browser - awesome!). They wanted a total of $129.85 if I wanted to pay the full "protection package". I'm paraphrasing here.


So I look into other solutions. I finally found one over at This one worked, their recommended malware removal tool apparently got rid of my "Security Tool" and for one - time removal they charged nothing. Nada. Very nice gesture.


For their capabilities I'm strongly thinking of purchasing them for ongoing protection if I ever feel I need one!

There are 4 pages of directions on how exactly to remove "Security Tool":

Automated Removal Instructions for Security Tool using Malwarebytes' Anti-Malware:

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

  2. Before we can do anything we must first end the processes that belong to Security Tool so that it does not interfere with the cleaning procedure. To do this, download the following file to your desktop. Download Link

  3. Once it is downloaded, double-click on the in order to automatically attempt to stop any processes associated with Security Tool and other Rogue programs. Please be patient while the programs looks for various programs and closes them. When it has finished, the black window will automatically close. While rkill is running, if you get a message stating that rkill, or another executable, is an infection, ignore it, and let finish. This is just the infection trying to stop rkill from disabling it. Please note, you may have to attempt to run rkill quite a few times before the malware process is terminated.

    Do not reboot your computer after running rkill as the malware programs will start again.

  4. Now you should download Malwarebytes' Anti-Malware, or MBAM, from the following location and save it to your desktop:

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

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

  7. 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 and is at the last screen, make sure you uncheck both of the Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware check boxes. Then click on the Finish button. If Malwarebytes' prompts you to reboot, please do not do so.

    If you receive a code 2 error while installing Malwarebytes's, please press the OK button to close these errors as we will resolve them in future steps. The code 2 error will look similar to the image below.

  8. As this infection deletes a core executable of Malwarebytes' we will need to download a new copy of it and put it in the C:\program files\Malwarebytes' Anti-Malware\ folder. To download the file please click on the following link:

    Malwarebytes' EXE Download
    When your browser prompts you where to save it to, please save it to the C:\program files\Malwarebytes' Anti-Malware\ folder. When downloading the file, it will have a random filename. Please leave the filename the way it is as it is important that it is not changed. You may want to write down the name of the file as you will need to know the name in the next step.

  9. Once the file has been downloaded, open the C:\program files\Malwarebytes' Anti-Malware\ folder and double-click on the file you downloaded in step 8. MBAM will now start and you will be at the main program screen as shown below.

  10. Before you can perform a scan, you must first update the program. To do this click on the Update tab, and that at the new screen click on the Check for Updates button. Malwarebytes' will now check for new updates and download and install them as necessary. When the update is completed, you will be prompted with a message stating either that you already have the latest updates or that they have been updated. Either way, you should now click on the OK button to continue.

  11. Now click on the Scanner tab and make sure the the Perform full scan option is selected. Then click on the Scan button to start scanning your computer for Security Tool related files.

  12. MBAM will now start scanning your computer for malware. This process can take quite a while, so we suggest you go and do something else and periodically check on the status of the scan. When MBAM is scanning it will look like the image below.

  13. When the scan is finished a message box will appear as shown in the image below.

    You should click on the OK button to close the message box and continue with the SecurityTool removal process.

  14. You will now be back at the main Scanner screen. At this point you should click on the Show Results button.

  15. A screen displaying all the malware that the program found will be shown as seen 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 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.

  16. 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.

  17. You can now exit the MBAM program.

  18. Due to the fact that this infection deletes certain MalwareBytes' files, and we had to work around this, if you wish to continue using MalwareBytes' Anti-Malware, which we suggest you do, then you should uninstall and then install it again so that the files are created properly.
Your computer should now be free of the SecurityTool 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.
