Why are you deleting a certain file in the first place? Is it a file that you no longer need or is it a spyware file that you must delete in order to remove a rogue anti-spyware program or a Trojan infection? Either way, there are a few ways you can go about deleting a protected file or spyware file from your computer. Follow the steps below to remove or delete protected files or spyware files that may have an "Access Denied error". (via)
