Security Tool is a misleading application that reports false errors on the computer. The software tries to fool the user to purchase the license version in order to remove the false infections.

I have received a lot of responses from people who have been infected by this misleading application. I have found removal instructions that are well defined and should solve for this problem.

Important: If you are unable to start your Antivirus software, you will need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode.

For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.

After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

How to delete the value from the registry

Important: It’s strongly recommended that you back up the registry before making any changes to it. Incorrect changes to the registry can cause your computer to stop running normal. Only modify the specified subkeys only. Please read the document on how to backup your registry.

  1. Click Start > Run.
  2. Type regedit
  3. Click OK.
  4. Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

  5. Navigate to and delete the following registry entry:
  6. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\”[RANDOM NAME]” = “C:\DOCUME~1\ALLUSE~1\APPLIC~1\[RANDOM NAME]\[RANDOM NAME].exe”

  7. Navigate to and delete the following registry subkey:
  8. HKEY_LOCAL_MACHINE\SOFTWARE\[RANDOM NAME]

  9. Exit the Registry Editor.

Please let me know if this information has helped in the removal of Security Tool.
