There are known issues when running any version of Symantec File Share Encryption (previously PGP NetShare) and McAfee VirusScan Enterprise 8.8 patch 2 at the same time.
The problem is seen with Office 2010 ".xlsx" and ".pptx" files in a File Share Encryption protected folder that cannot be opened on Microsoft Windows 7 64-bit systems if McAfee version 8.8 is installed.
Microsoft Office documents in a File Share Encryption protected folder cannot be opened and are marked as "corrupted" if McAfee VirusScan is running at the same time.
The problem was introduced with a design change in McAfee VirusScan Enterprise 8.8 patch 2 where the vendor moved from a "Legacy Filter Driver" to the "Minifilter Driver Model". Symantec File Share Encryption (PGP NetShare) uses the Legacy Filter Driver model which is no longer supported by McAfee 8.8 patch 2, even though this design is still supported by Microsoft. The problem affects any version of Symantec File Share Encryption and does not occur when using an older version of McAfee VirusScan prior to 8.8 patch 2 (for example, version 8.8 patch 1).
The following workarounds exist:
- Uninstall or disable McAfee VirusScan or install a version of McAfee VirusScan Enterprise previous to version 8.8 patch 2.
- If the File Share Encryption component is not needed, install the Symantec product without any File Share Encryption/PGP NetShare components. See article HOWTO84112 for details.
- Decrypt the protected folder. The files that appeared to be corrupt, will then open successfully.
Office 2010 .xlsx and .pptx files in a folder protected by Symantec File Share Protection (PGP NetShare) cannot be opened on Windows 7 64-bit if McAfee 8.8 patch 2 is installed
