Security System virus removal

The security System virus showed up on my computer over the weekend. I read about installing malware removal software to my desktop, closing all windows, and then opening the malware revoval file from the desktop. Unfortunately, none of my programs on my desktop will open. I cannot open the Window task manager or any other programs. I receive an error (from the security system program) that the file NAVAPSVC.EXE is infected. This computer is on a network, and I am concerned that this could spread to the rest of my network. How can I remove this virus?
Thank you

Please download the current version of HijackThis from HERE

• Double click and run the installer.
  
• It will install to C:\Program Files\Trend Micro\HijackThis\hijackthis.exe
  
• After installing, you should get the user agreement, press accept and Hijack This will run.
  
• Select Do a system scan and save a log file. This will open a notepad file of everything Hijack This found, copy and paste it back here.

How to remove the Security System
go to My computer, C drive location, Program files......where this nasty security is installed change the name of the file from 11128800 to anything like garbage
Also go to the exe file of this via going to the icon right clik and properties and change the name
Then this sucker won't work got to task manager etc stop the exe and start deleting the file
