So did you reformat the drive or are you just trying to get rid of the virus by using virus scan? Some viruses get so deeply embedded that you have to manually remove them. Again here is a link to the free avg site. It's the download on the lower right. What you might want to do is run a dxdiag on your computer after everything is done. You do this by going to the start button, select 'run', type in dxdiag, this bring up a window with several buttons on it, click the 'save all information' button, and it will create a wordpad document that you can save to your desktop. Read through it and see if anything is failing. It will also give you the make and model number of your machine which will help me find the instructions on how to go about cleaning it up. Good luck
