Norton antivirus software is concerned is the presence of corrupt files that we cannot delete them completely. Have you ever installed your antivirus successfully but cannot remove a corrupt file completely? I guess so, and if that is the case, you are aware of the fact that even after identifying some corrupt files, scanning the whole system and deleting them, you may at some point in time realize that the corrupt files are still in existence. No matter how much you try to do away with them, the files will still remain.
