Replie to your problem
i have also encountered this problem once before; it took me a day to figure out and get rid of, if you havent got the background off the desktop it means that there's stil spyware on your computer. I have found that norton antivirus and microsoft antivirus don't work at all, if you use the restore to a previous date feature then it will still also come back. It was quite a while since that last happened to me however, you can wipe the hard drive *if you're not sure how to do so i will post further details* and i will get back to you with the solution i used soon. Hope you can get it workin
