SYMPTOMS
| • | On a Windows Server 2008-based or Windows Vista Service Pack 1 (SP1)-based computer, an application writes to a file on a local file share. |
| • | This file is scanned by using memory-mapped files. This scanning process typically occurs when certain antivirus software is installed on the computer. |
In this scenario, additional character spaces may be added to sections of the file. Therefore, the file becomes corrupted.
