原因

The nVidia driver nview.dll is intercepting McAfee software calls and ShStat reissues the request. The reissue results in a looping state because the nview.dll driver keeps intercepting it.

解决方案

Update to the latest nVidia Windows driver. Download and install the latest driver from: http://www.nvidia.com.

Also, update to the latest VSE 8.x patch. Patches are cumulative; Technical Support recommends that you install the latest one.

Updates are available when you log on to the ServicePortal.

解决方法

Turn off the nView Desktop Manager:

Click, Start, Settings, Control Panel.
Double-click NVIDIA nView Desktop Manager.
Select Desktop Management.
Click Disable, and then click OK.
Exit the Control Panel and restart your system.
