fshoster32.exe process remains on after Citrix logoff

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:

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.
