SYMPTOMS
When you try to use Microsoft Visual Studio .NET or Microsoft Visual Studio 2005 on a computer that has McAfee VirusScan antivirus software enabled, you may notice one or more of the following behaviors:  When you try to start Visual Studio .NET or Visual Studio 2005, the development environment may stop responding, and you may receive the following error message:

An unhandled exception has been caught by the VSW exception filter

Note This problem occurs regardless of whether Script Blocking is turned on or off for the McAfee antivirus software. When you try to close Visual Studio .NET or Visual Studio 2005, the environment may stop responding. .NET Framework Installation Wizard may stop responding at the end of the setup procedure.



CAUSE
This occurs because an antivirus program or a firewall program is running during the installation of Visual Studio .NET or of Visual Studio 2005. Visual Studio .NET or Visual Studio 2005 Setup has custom actions in VBScript that stop responding or cause problems if you have antivirus script blockers such as those in an antivirus program or a firewall program turned on.
