Removal of Security Tool. Help please?

I have this awful Security Tool fake spyware thing on my computer, and I can't even use Norton disk as it is not recognised. Any clues please?

Hello.

Download OTL by OldTimer to your Desktop.

• Close all windows and double click OTL.exe
  
• Click Run Scan and let the program run uninterrupted
  
• It will produce two logs for you, one will pop up - OTL.txt, the other will be saved on your Desktop - Extras.txt. Post both logs in this thread.
  
• You may need to use two posts to get it all.
  

Thanks so much. Will give it a go.

Awaiting logs.
