It is very simple to remove on your own.
1. Turn your computer on and press f8
2. At the advanced startup screen find Start Windows in safe mode
3. Press Enter
4. Once finished loading windows look for an icon that says security tools
5. Right Click it and find the location of the file
6. Give yourself privilages to view hidden folders
7. Go to the location of the Security Tools Folder usually xxxxxxx with x being any number 0-10
8. Delete the folder
9. Run a virus scan
10. You deserve a cookie ( a real one)

I have security tool on my PC and have tried every thing to get it off, my PC will not start in safe mode, I cannot access task manager and can not download any anti virus, or malware programs. I am stuck, help!!!

Kevin October 22nd, 2022 at 12:53 pm

Here’s how I finally got rid of this thing. At times, it would go “dormant” where the desktop and many functions would return. I finally managed to download the free version of AVG after two unsuccessful attempts and ran a virus scan. Several items came up as “unhealed” (all of which had file names with eight random numbers) so I went into “Search”, entered the numbers and manually deleted the files through “Edit” and “Delete”. I still don’t have System Restore or Windows Updates capabilities, but everything else has returned to normal. Hope this helps

i scared to much…!!!

Barntha Lemen October 23rd, 2022 at 12:15 am

Same thing happened to my computer. the security tool will not go away for anything and safe mode won’t work. the computer itself won’t even turn on and i am soooo pissed about the whole virus. lsas.blaster is the worst thing that has ever happened to me. Itunes won’t work and my songs are being deleted.. Any help?

Patti Dever October 31st, 2022 at 3:10 pm

I have tried everything you have suggested above. The security tool will not allow me to run the process explorer or download the removal tool.

Sara November 14th, 2022 at 1:14 pm

Hei, jeg får ikke fjernet viruset. Når jeg prøver å åpne linkene hindrer programmet meg i å åpne dem… HJEEEEEEEEEEEEEEEEEEEEEEEEELP!

jeannine November 30th, 2022 at 4:02 am

hello. i need help. i have tried everything here. i found the file but it just says it can not delete it because it is in use. i can not open task manager or any other virus software because the security tool virus blocks it and says it has a worm detected. please help. i am desperate!

inge December 14th, 2022 at 8:10 pm

Jeg har forsøkt å laste ned et par forskjellige programmer som skal ta knekken på Security Tool. Går greit å få laste det ned, men når jeg skal kjøre det virker det som om det blir stoppet av virus-programmet… Prøvde også å laste det ned og lagre det med et annet navn, men ble stoppet da også. Har også prøvd å gå inn i “oppgavebehandling” for manuelt å stoppe prosessen som kjører Security Tool, men virusprogrammet har kontroll over det også… Noen som vet hva jeg kan gjøre???

Claus December 20th, 2022 at 12:11 am

Try to get a taskmanager up and running as fast as possible after reboot, if you succeed in doing this before the virus get started, you will stil have control over the taskmanager. Now stop the virus by means of the taskmanger and run msconfig and remove the virus from the startup tab in msconfig. You should now have gained control over your computer again, follow the instructions on this page to actually remove the virus from your system. Good luck !!

Christopher December 21st, 2022 at 10:23 pm


You can’t do anything when the program is popping up on your window all the time.
And you can’t start your computer in safe mode because then you will get a blue screen.

How I solved the problem was to use; and boot up on the cd which comes with the program. You can’t boot up on windows because then the virus will just be in charge.
What you have to do is to boot up on the oo cd disc media exactly when you start the computer. And use the rededit tool from oosoftware which is including in the product.
Then I just searched for the [random numbers].exe and deleted them.

Hope this helps, good luck!

That was a huge help. Thanks very much. It is nice to see a polite explanation of how to remove these things manually without being forced to download another file that could be a trojan.
The only part that I couldn’t complete was “Block Security Tool Related Websites” because I have no idea where I got it from. It would be great if people could post here the sites they got it from so we can all share and learn from the experience.

TJP February 21st, 2023 at 2:06 am

Thanks so much. I was able to take SecurityTool off a friend’s LT using your instructions. However, everyone attempting to do that should know that when you try to “end process” in Task Manager the confirmation dialog, which you must answer, will come up in the middle of the screen and may be immediately hidden by another Security Tool pop-up window, making you think that “End Process” isn’t working either. If it seems like “End Process” isn’t working, just try moving (not closing) the Security Tool windows aside and see if the confirmation dialog is there.

I am trying all suggestions to remove this virus, but nothing is working. Evertyhing I try is blocked. I have just started using Windows 7 instead of Windows XP and I can’t find Documents & Settings on the C:/. Can you lead me in the right direction?

Bjørn March 24th, 2023 at 5:08 pm

Ik heb op de laptop van mijn zoon het security tool virus zitten.
Heb Malwarebytes geinstalleerd, maar krijg dit programma niet open. Kunt u mij helpen?

riley April 9th, 2023 at 2:10 am

I recently dealt with this annoying, yet very defensive virus. Here’s how I accomplished removing it:
1. If you’re using a Windows Operating System, first go to the Start menu and click on ‘Shutdown’. (otherwise shut down your computer how you normally would)
2. Turn on your computer manually using the power button and boot the system in Safe Mode by repeatedly tapping the F8 key. You’ll reach a black screen with with text prompting you to choose the booting method. Use the arrow key to highlight “Safe Mode” then press Enter.
3. Once in Safe Mode, login as you normally would. The Security Tool virus configures itself to automatically run at startup. However, safe mode will only start system services, thus preventing this pesky virus from starting.
