My PC was hijacked and I have managed to get rid of all the junk but now I am unable to change my desktop backgound. It is grayed out. I keep getting some wierd screan (from the former hijacking). I have found the location of the file (///c:windows/privacy_danger/index.htm) and have deleted it. Something is running somewhere and it must also be in my startup. Once I deleted the file above, every so often, I get a message that the file ///c:windows............ can't be found. All I have is white screen. My questions are: how do I unlock the Desktop and get it un-grayed so I can make a selection and would you know where I would find the process that is running - looking to launch the ///c:windows/........  file. Any help would be greatly appreciated..  Thanks
