[SOLVED] Computer so slow I can't get on it

I am trying to open a browser to access ccleaner for cleaning HD and to download a spyware program as this computer, Dell laptop Inspirion, may have spyware. It is so slow that I may click on IE and it may take 5 minutes before a window pops up. Am I able to burn ccleaner from another computer and then run it from the CD drive to clean it the HD enough to download a spyware program, or what would you recommend?

thank you
