On a computer that is running Microsoft Antigen 9.0 for Exchange with Service Pack 1, the AntigenInternet.exe process may stop responding. Additionally, an event that displays bucket ID 367405185 is logged in the Application log.
This issue occurs when the AntigenInternet.exe process tries to communicate with the AntigenService.exe process. However, this communication fails because the reference to AntigenService.exe was not initialized.
To resolve this issue, install Hotfix Rollup 4 for Antigen 9.0 for Exchange with Service Pack 1.
