What is Security Tools?
Security Tool is a rogue anti-malware scanner and it is often installed from malicious advertisements, malware or Trojan downloaders. When Security Tool is installed by a Trojan, the scareware program will either automatically launch itself or the user is prompted to execute another installation after a system reboot.
If the computer is rebooted, the Security Tool program will change the desktop background, covering the desktop icons. It will also block any applications that the user wants to use such as the browser, notepad, and legitimate anti-virus, anti-spyware or anti-malware program. The important utilities in Windows such as Task Manager, Registry Editor and the Startup Manager console in Windows are blocked by Security Tool. The rogue program will display fake warning message, information of non-existing threats in Windows and a fake Windows Security Center alert icon.
You can remove Security Tool by using free malware removal or by manually deleting added files, folders and registry values or registry keys.

Removing Security Tool if the PC Has Not Restarted
When you first see the Security Tool rogue program in Windows, the desktop background is not modified. If you have not restarted the computer, you can easily remove Security Tool using the Microsoft Windows Malicious Software Removal Tool that is already installed in your computer. It is not blocked by Security Tool because you have not yet restarted the computer, which will allow the rogue program to block it. Simply click Start, type mrt.exe in the Run Box and then hit the Enter Key on the keyboard. The Malicious Software Removal Tool will open.
You only need to manually delete the now non-functioning Security Tool desktop shortcut after the Malicious Software Removal Tool automatically removes the scareware program.
You can also use your browser to download EmsiSoft Anti-Malware, Malwarebytes Anti-Malware, Windows Defender, SUPERAntiSpyware or Spybot - Search & Destroy. Not only that, you can also still update those programs and have the latest definitions and the best chance for removing Security Tool. This is true only if you have not restarted the computer, if the desktop background is not changed and if the legitimate anti-malware program requires no PC restart after installation.

Removing the Security Tools Virus if Anti-spyware or Anti-malware is Blocked
