I am using Vista and getting access denied permission while deleting a file. I never got that error and somehow it started appearing on its own. The laptop use to work fine. There was some virus issue but that was resolved. The virus appeared from the mp4 player. At that point Quickheal showed up a set of warning and it says that it has cleared the same. I am not able to understand why the issue appear. There is no virus and I am the system admin.
