Issue:
When a Citrix application is published for end users, traces of the server's F-Secure Server Security session also follows. Visible effects are:
- when the user logs off the Citrix session, the F-Secure process fshoster32.exe remains running
- an F-Secure system tray icon becomes visible on the end-user's desktop
- performance degradation due to many fshoster32.exe processes running.
When the user's fshoster32.exe process is ended manually on the Citrix side, the icon disappears and the user's session closes.
Resolution:
This has been mitigated with the release of Server Security 14.10. If you have obstacles preventing you from a direct upgrade, you can follow the workaround instructions laid out below.
For more information about this situation and a suggested registry change that can be used to end processes together with the main executable, read the following Citrix knowledge base article: Graceful Logoff from a Published Application Renders the Session in Active State.
The following registry key has been confirmed by customers:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI
Value Name:LogoffCheckSysModules
Type:REG_SZ
String:fshoster32.exe
Make sure to familiarize yourself with the information from Citrix before making any changes to your environment. Also, confirm with a small scale test before pushing changes to production.
